In this paper we present a new methodology for producing 3D clothes, with realistic behavior, providing users with an apposite feel for the garment's details. The 3D garments that are produced, using our methodology, originate from 2D CAD patterns of real garments and correspond to the regular sizes that can be found on a shop floor. Our aim is to build a compelling, interactive and highly realistic virtual shop, where visitors can choose between many different types of garments designs and proceed to simulate these garments on virtually animated bodies. By merging the approach often used by the fashion industry, in designing clothes, and our own methodology for creating dressed virtual humans, we present a new technique providing trouble-free and straightforward garment visualization. The entire process starts from the creation of virtual bodies (either male or female), using standard measurements, which form the basis for garment modeling. Using splines, the 2D garment patterns are created and then seemed together around a virtual human body, providing the initial shape. A simulation is made using the seemed garment by applying physical parameters based on real fabric properties. Once the garment has been created, a real time platform, which has been embedded inside a web browser, is used as an interface to the Internet. We extend the web interface to add interactivity and the ability to dynamically change textures, clothes, body measurements, animation sequences and certain features of the virtual environment. The whole methodology does not aim to build only a virtual dressing room, where customers can view garments fitted onto their own virtual bodies but to visualize made-to-measure clothes, animate them, visualize the cloth behavior and to add interactivity. The entire Virtual Try-On experience is a process of targeting the clientele, designing the clothing collection, dressing the virtual models and then using the web as a virtual shop floor.
