The Uniform Project
Came across this curious site: TheUniformProject.com
Apparently it documents an attempt by an enterprising girl to try out sustainable fashion, by wearing the same dress (or rather seven copies of the same dress) for an entire year. And wouldn't you know it, the design she chose buttons down the back! Of course for versatility she wears it the other way as well, but certainly quite topical.
On another note, check out this cute top on Flickr.
