I found this site about an hour ago and have been salivating over it ever since...
Mill Crest Vintage is one of the best vintage clothing sites I have seen yet (although it is a bit pricey). I love the variety and it seems like it would be pretty easy to determine your size, unlike many other sites I have visited.

Here are a few of my favs!!
