That's what I'm working on right now! So much customization, so many layers you can mix and match. And you can change body type as well, there's a female and male body type for you to pick. The clothes will look different on each body type. You can pick the colour for any of the clothes (and its details!), and also change your own hair or eyes etc.
It's a dress-up game as well after all, gotta have customization.
