Does this software also support Customization of the Shirts like Color, Cloth selection, Fabric, Fleets, Buttons, Pocket, Design, Collar…etc?
Well, The software you are talking about is a SHIRT customization tool but not a design customzation software. Here is an example: http://beta.creyate.com/en/gcustomise1/Mens-Shirt/103/SHIRT3/
The one you see here is a product designer and its for creating PRINTING output not a complete PRODUCT.
