  In this demo, we present Chat-to-Design, a new multimodal interaction system
for personalized fashion design. Compared to classic systems that recommend
apparel based on keywords, Chat-to-Design enables users to design clothes in
two steps: 1) coarse-grained selection via conversation and 2) fine-grained
editing via an interactive interface. It encompasses three sub-systems to
deliver an immersive user experience: A conversation system empowered by
natural language understanding to accept users' requests and manages dialogs; A
multimodal fashion retrieval system empowered by a large-scale pretrained
language-image network to retrieve requested apparel; A fashion design system
empowered by emerging generative techniques to edit attributes of retrieved
clothes.
