I might be able to help, but I need your size in cm. What kind of clothes are you looking for as well? Jeans? Tops? Funky subculture stuff? Girly suff?

I kinda know where to get a lot of clothes, and if they fit a 5'6 average American I'm sure they can fit you :x you're not like....morbidly obese large, so it's still find-able.
