StyleMe! is a fantastic fashion-app on the iPhone. This program has been designed to help women choosing their clothes and make combinations quickly.
The idea is very simple:
1) Take some shots of yourself with different clothes (with a mirror or with a friend)
2) Cut yourself into 4 parts with the in-app "slicer"
3) Combine manually or push the "reload" button to combine randomly
4) Save the combination.
5) Finally, you can export saved pictures on your iPhone library and send them by e-mail, MMS etc.
