- Abstract: E-commerce is growing at an unprecedented rate and the fashion industry has
recently witnessed a noticeable shift in customers' order behaviour towards
stronger online shopping. However, fashion articles ordered online do not
always find their way to a customer's wardrobe. In fact, a large share of them
end up being returned. Finding clothes that fit online is very challenging and
accounts for one of the main drivers of increased return rates in fashion
e-commerce. Size and fit related returns severely impact 1. the customers
experience and their dissatisfaction with online shopping, 2. the environment
through an increased carbon footprint, and 3. the profitability of online
fashion platforms. Due to poor fit, customers often end up returning articles
that they like but do not fit them, which they have to re-order in a different
size. To tackle this issue we introduce SizeFlags, a probabilistic Bayesian
model based on weakly annotated large-scale data from customers. Leveraging the
advantages of the Bayesian framework, we extend our model to successfully
integrate rich priors from human experts feedback and computer vision
intelligence. Through extensive experimentation, large-scale A/B testing and
continuous evaluation of the model in production, we demonstrate the strong
impact of the proposed approach in robustly reducing size-related returns in
online fashion over 14 countries.

Virtual try-on (VTO) applications aim to improve the online shopping experience by allowing users to preview garments.
Many VTO tools fail to consider the crucial relationship between a garment's size and the user's body size.
We introduce SiCo, an online VTO system, where users can upload images of themselves and visualize how different sizes of clothing would look on their body.

We propose an improved model named Relation Enhanced Attention Recurrent (REAR) network.
Compared to KERN, the REAR model leverages not only the relations among fashion elements but also those among user groups.
To further improve the performance of long-range trend forecasting, the REAR method devises a sliding temporal attention mechanism.

PreSizE is a novel deep learning framework which utilizes Transformers for accurate size prediction.
We demonstrate that PreSizE is capable of achieving superior prediction performance compared to previous state-of-the-art baselines.
As a proof of concept, we demonstrate that size predictions made by PreSizE can be effectively integrated into an existing production recommender system.

We propose a novel fashion collocation framework, Neural Graph Filtering, that models a flexible set of fashion items via a graph neural network.
