# FashionPose: Text-Driven Fashion Visualization

FashionPose is a unified, text-driven framework for personalized fashion visualization that converts a natural-language prompt into a pose-aligned, high-fidelity, relit person image. Its defining claim is that the same caption serves as the sole high-level control signal for geometry and photometry: the system first predicts a 2D human pose from text, then synthesizes a person image with a diffusion model, and finally applies a lightweight relighting module, again under prompt control. In this formulation, explicit pose annotations are removed from the user-input stage, while pose alignment, garment rendering, and lighting adaptation are integrated into a single pipeline [2507.13311].

## 1. Conceptual scope and problem setting

FashionPose is organized as a three-stage pipeline: **Text-to-Pose (T2P)**, **Pose-to-Image (P2I)**, and **prompt-conditioned relighting**. The first stage maps a caption to a COCO-style 2D skeleton; the second stage generates a fashion image conditioned on the predicted pose and a source image; the third stage adjusts illumination with a lightweight module based on IC-Light. The framework is described as “unified” because the same prompt controls all three stages, and “text-driven” because natural language replaces explicit pose specification at the interface level [2507.13311].

This design places FashionPose within a broader transition in fashion generation from explicit pose-conditioned synthesis toward language-mediated control. Earlier fashion-generation systems generally required a user-specified target pose, keypoint heatmap, DensePose map, or a parametric body representation. FashionPose instead makes pose itself a predicted latent target of language supervision. A plausible implication is that the framework is intended not merely as pose-guided synthesis, but as a prompt-native interface for fashion visualization.

The practical motivation is fashion e-commerce. The framework is presented as relevant to virtual fashion previews, personalized catalog visualization, model reposing without manual pose annotation, and lighting adaptation for different marketing styles. In that sense, FashionPose addresses both **body configuration** and **illumination style**, rather than treating them as separate downstream editing problems [2507.13311].

## 2. Text-to-Pose prediction

The T2P module predicts a 2D pose from a caption \(C\), producing joint coordinates \(\hat{\mathbf P}=\{(\hat x_i,\hat y_i)\}_{i=1}^{18}\) and visibility logits \(\hat{\mathbf v}\). The text encoder is a **frozen CLIP text encoder** that yields a 768-D embedding \(\mathbf e_C\). This embedding is passed through a **2-layer MLP** with dimensions \(768 \to 1024 \to 512\) and GELU, combined with a learnable positional vector, and then processed by a **6-layer, 8-head Transformer encoder**, yielding \(\mathbf x_{\mathrm{Trans}}\in\mathbb R^{512}\). From this shared latent, the network branches into four heads: a pose head, a visibility head, a text projection head, and a pose projection head. The text and pose projections are \(\ell_2\)-normalized and used for contrastive alignment [2507.13311].

The learning objective combines five losses. The coordinate loss supervises visible joints with masked \(L_2\):
$$
L_{\mathrm{coord}}= \frac{\sum_i m_i[(\hat x_i-x_i)^2+(\hat y_i-y_i)^2]} {\sum_i m_i+\epsilon}.
$$
The visibility loss is binary cross-entropy:
$$
L_{\mathrm{vis}}= -\tfrac1{18}\sum_i\bigl[v_i\log\hat v_i+(1-v_i)\log(1-\hat v_i)\bigr].
$$
For occluded joints, an invisible-joint penalty regularizes coordinates toward the origin:
$$
L_{\mathrm{inv}}= \frac{\sum_i(1-v_i)(\hat x_i^{2}+\hat y_i^{2})} {\sum_i(1-v_i)+\epsilon}.
$$
Skeleton consistency is enforced over the COCO edge set \(\mathcal E\):
$$
L_{\mathrm{skel}}= \frac1{|\mathcal E|} \sum_{(i,j)\in\mathcal E} \bigl(\lVert\hat{\mathbf P}_i-\hat{\mathbf P}_j\rVert_2 -\lVert\mathbf P_i-\mathbf P_j\rVert_2\bigr)^2.
$$
Finally, text and pose embeddings are aligned with a bidirectional InfoNCE term:
$$
L_{\mathrm{con}}= \frac1{2B}\sum_{p=1}^{B} \Bigl[-\log\frac{e^{s_{pp}}}{\sum_q e^{s_{pq}}} -\log\frac{e^{s_{pp}}}{\sum_q e^{s_{qp}}}\Bigr],
$$
where \(s_{pq}=(\mathbf f^{\text{text}}_p\cdot \mathbf f^{\text{pose}}_q)/\tau\) and \(\tau=0.07\). The total objective is
$$
L_{\text{total}}= L_{\text{coord}}+ L_{\text{vis}}+ \lambda_{\text{inv}}L_{\text{inv}}+ \lambda_{\text{skel}}L_{\text{skel}}+ \lambda_{\text{con}}L_{\text{con}},
$$
with \(\lambda_{\text{inv}}=0.50\), \(\lambda_{\text{skel}}=0.10\), and \(\lambda_{\text{con}}=0.10\) [2507.13311].

The role of this stage is central. The framework’s main departure from conventional pose-guided fashion generation is that target geometry is not externally provided as a control map; it is inferred from language. The ablation study attributes major gains to the Transformer and especially to the contrastive branch: removing the Transformer drops **PCK@0.05** from **0.281** to **0.065** and raises **MPJPE** from **35.85** to **64.82**, while adding the contrastive branch raises **PCK@0.05** to **0.499**, lowers **MPJPE** to **22.65**, and yields **Vis. mAP = 0.988** [2507.13311].

## 3. Pose-to-Image diffusion synthesis

The P2I stage is a diffusion-based generator conditioned on a **source/reference image** \(I_s\), a predicted **target pose** \(\mathbf p_t\), and the **source pose** \(\mathbf p_s\). It forms paired inputs
$$
I_{\mathrm{pair}}=[I_s;Z],
$$
where \(Z\) is a zero canvas of the same resolution, and
$$
H_{\mathrm{pair}}=[H(\mathbf p_t);H(\mathbf p_s)],
$$
where \(H(\mathbf p_t)\) and \(H(\mathbf p_s)\) are Gaussian joint heatmaps of size \(18\times64\times64\). These heatmaps preserve spatial structure before the UNet [2507.13311].

Two frozen encoders define the conditioning prior. **DINO-v2** encodes the source image into appearance tokens
$$
\mathbf z_s=f_{\mathrm{DINO}}(I_s)\in\mathbb R^{256\times768},
$$
and the **CLIP image branch** encodes the target-pose heatmap into
$$
\mathbf e_p=f_{\mathrm{CLIP}}(H(\mathbf p_t))\in\mathbb R^{512}.
$$
An autoregressive prior samples a target token sequence \(\hat{\mathbf z}_t\in\mathbb R^{256\times768}\), conditioned on \(\mathbf z_s\), \(\mathbf p_t\), and \(\mathbf e_p\), with loss
$$
\mathcal L_{\text{AR}} =-\sum_{k=1}^{256} \log p_\theta\!\bigl(z_{t,k}^\star\mid \hat{\mathbf z}_{t,<k}, \mathbf z_s,\mathbf p_t,\mathbf e_p\bigr).
$$
This prior is intended to maintain appearance consistency while adapting to the target pose [2507.13311].

Identity preservation is implemented through masked latent initialization. With a face-and-hair mask \(M\), the initial diffusion state is
$$
\mathbf x_T=(1-M)\odot I_s+M\odot\mathcal N(0,\mathbf I),
$$
with \(T=400\). In parallel, pose is injected at every UNet scale \(l\) by concatenating a resized pose tensor:
$$
\mathbf h^{(l)} \leftarrow [\mathbf h^{(l)};\pi_l(H_{\mathrm{pair}})],
$$
where \(\pi_l\) bilinearly resizes the heatmaps to the current resolution. The diffusion loss is
$$
\mathcal L_{\text{diff}} =\mathbb E\!\left[ \tfrac12\lVert\varepsilon- \varepsilon_\theta(\mathbf x_t,t)\rVert_2^2 +\lambda_{\text{id}}\lVert(1-M)\odot\bigl(g^{-1}(\mathbf x_0)-I_s\bigr)\rVert_1 \right],
$$
with \(\lambda_{\text{id}}=10^{-2}\). A pose-feature contrastive alignment term is also added:
$$
\mathcal L_{\text{pose}} =-\log \frac{\exp\!\bigl(\langle\mathbf e_p,\mathbf f_p\rangle/\tau\bigr)} {\sum_{q}\exp\!\bigl(\langle\mathbf e_p,\mathbf f_q\rangle/\tau\bigr)}.
$$
The complete objective is
$$
\mathcal L_{\text{P2I}} =\mathcal L_{\text{AR}} +\mathcal L_{\text{diff}} +0.05\,\mathcal L_{\text{pose}}.
$$
At inference, the model uses **50 DDIM steps** and classifier-free guidance weight \(\gamma=1.5\) [2507.13311].

This stage differs from earlier pose-guided image synthesis in two ways. First, it is downstream of a text-conditioned pose predictor rather than an externally supplied pose map. Second, identity preservation is not left entirely to adversarial or reconstruction priors; it is made explicit through face-and-hair masked initialization and an identity loss term. The reported qualitative comparisons claim sharper garment seams and buttons, better texture detail, and more plausible completion of occluded clothing than ADGAN, PISE, GFLA, DPTN, CASD, NTED, PIDM, and PCDMs [2507.13311].

## 4. Prompt-conditioned relighting

The third stage is a lightweight relighting module based on **IC-Light**. It operates after person-image synthesis and uses the same natural-language prompt to adjust illumination. The relighter modifies **light direction**, **color temperature**, and **intensity**, while preserving **garment texture**, **facial identity**, and **scene coherence**. Example prompts shown for this stage include “sunshine from window,” “sunset over sea,” “golden hour,” “soft studio lighting,” and “RGB glow” [2507.13311].

The relighting module is described as lightweight because it leverages a pretrained diffusion-based relighter rather than training a new relighting model from scratch. Its placement at the end of the pipeline is architecturally significant: pose synthesis and illumination adaptation are decoupled, but both remain prompt-conditioned. This suggests a modular design in which geometry is stabilized before photometric variation is introduced.

Within the logic of FashionPose, relighting is not an ancillary post-processing step. It is one of the framework’s defining components, because the method is explicitly framed as **text-to-pose-to-relight** generation rather than text-to-pose or pose-to-image alone. A common misunderstanding is to equate the framework with standard pose-guided generation plus a separate lighting editor; the paper instead treats prompt-sharing across geometry and photometry as the unifying principle [2507.13311].

## 5. Data, supervision, and empirical performance

A key enabling resource is **PoseCap**, a dataset of over **40k** image-caption-keypoint pairs built from **DeepFashion**. Its construction pipeline uses **YOLOX** to filter images, resizes them to \(256\times256\), applies **Qwen-VL** to generate pose-focused captions, and uses **OpenPose** to extract 18 keypoints. Each sample is stored as \(\langle C, K\rangle\), where \(C\) is a caption and \(K\) the corresponding keypoints. PoseCap is specifically intended to support the text-to-pose module by grounding language in 2D geometry [2507.13311].

The main quantitative evaluation of the pose stage is reported on **DF-PASS**, using **PCKh@0.5**, **MPJPE**, and **visibility mAP**. The published results are:
- **ControlNet**: **PCKh@0.5 = 0.808**, **MPJPE = 86.68**, **Vis. mAP = 0.800**
- **TIPS**: **PCKh@0.5 = 0.598**, **MPJPE = 68.20**, **Vis. mAP = 0.801**
- **FashionPose**: **PCKh@0.5 = 0.938**, **MPJPE = 44.43**, **Vis. mAP = 0.987** [2507.13311]

The paper also reports hyperparameter trends. Increasing hidden dimension from **384** to **640** improves PCKh and reduces MPJPE; a **4-layer Transformer** gives the best balance, while deeper models overfit; attention head count has little effect; **dropout = 0.05** works best, whereas **0.20** hurts performance; and temperature \(\tau=0.07\) is a strong default. These observations indicate that the T2P stage is sensitive to capacity and regularization, while being less sensitive to head count [2507.13311].

Implementation details are partially disclosed. **Text-to-Pose** training and evaluation use **one RTX 4090 GPU**, while **Pose-to-Image** uses **two H100 GPUs**. The paper also states that the dataset will be publicly released and that code will be open-sourced [2507.13311].

## 6. Position within fashion-pose research, distinctions, and limitations

FashionPose belongs to a broader family of fashion systems that use human geometry as an organizing variable, but it occupies a specific point in that landscape. Earlier work modeled pose and clothing through explicit pose maps, keypoint heatmaps, or parametric human representations. For example, “Pose Guided Fashion Image Synthesis Using Deep Generative Model” used an image encoder, a pose encoder, a decoder, and two discriminators to generate a photorealistic image under a target pose [1906.07251]. “Generating High-Resolution Fashion Model Images Wearing Custom Outfits” encoded a **custom outfit** and a **16-channel pose heatmap** into a StyleGAN-based conditional model at \(1024 \times 768\) resolution [1908.08847]. “FashionComposer: Compositional Fashion Image Generation” later extended pose conditioning with **SMPL-derived densepose**, multi-reference garment and face assets, and subject-binding attention, making pose an explicit controllable input inside a diffusion framework [2412.14168]. Against this trajectory, FashionPose’s main distinction is that pose is inferred from text rather than provided directly [2507.13311].

The framework is also distinct from adjacent multimodal and training-free systems. “Multimodal-Conditioned Latent Diffusion Models for Fashion Image Editing” injects pose as an **18-channel keypoint heatmap** alongside sketch, text, and texture for garment editing, but still assumes structured multimodal conditioning rather than text-to-pose prediction [2403.14828]. “ProFashion: Prototype-guided Fashion Video Generation with Multiple Reference Images” addresses pose-aware video generation with multiple reference views and keypoint motion flow, extending pose guidance into temporal coherence rather than language-mediated pose prediction [2505.06537]. “Training-Free Consistency Pipeline for Fashion Repose” is a zero-shot, consistency-first pipeline for normalizing long-sleeve garments into a **45-degree arm-to-torso pose**; despite surface similarity, it is a narrower non-rigid editing system rather than the same framework as FashionPose [2501.13692].

The wider literature shows that pose information has been useful beyond generation. “Fashion Apparel Detection: The Role of Deep Convolutional Neural Network and Pose-dependent Priors” fused CNN appearance with pose-conditioned geometric priors for apparel localization [1411.5319]. “Pose Guided Attention for Multi-label Fashion Image Classification” used OpenPose-derived heatmaps to supervise semantic attention in fashion recognition [1911.05024]. “Fashion is Taking Shape” connected SMPL-based body-shape estimation to clothing-category prediction, showing that shape is statistically informative for fashion understanding [1807.03235]. A plausible implication is that FashionPose should be viewed not only as a generative model, but as part of a larger research program in which body geometry mediates fashion representation, retrieval, prediction, and synthesis.

The paper states several limitations. The method relies on **precise captions**, supports only **global single-source illumination**, and may produce artifacts in **multi-light scenes**, with **complex materials**, or under **heavy occlusions**. It also identifies future work in **video support**, **3D body priors** for depth-aware edits, and **shorter diffusion schedules** for faster inference [2507.13311]. These limits matter when the prompt is ambiguous or the scene departs from the global-lighting, single-person assumptions implicit in the current design. The broader direction of fashion generation also points beyond studio-style outputs: “Virtual Fashion Photo-Shoots: Building a Large-Scale Garment-Lookbook Dataset” argues that garment-conditioned synthesis should move toward **dynamic poses**, **diverse locations**, and **carefully crafted visual narratives**, suggesting a future setting in which text-to-pose-to-relight frameworks may be coupled with editorial, context-rich supervision [2510.00633].
