the colours on the hat is my favourite part, and the shading :D
It's a pencil skirt with a seam down the middle. Tight skirts usually have a slit or a hidden pleat at the back for walking. ^_~
That, in the odd world of fashion, comfortable clothes are for wimps. Bwahaha. :P
Only thing is, her crotch ends right under her belt?! Or is that supposed to be a skirt with a seam in the middle? If so, then it's a pretty tight one (guess she won't be able to walk with that ... but that's the odd world of fashion, right? 
)
The face reminds me alot of a young Madonna, only not blonde!
It's a very impressive piece of work though, great use of colours!!
Lovely work!
