Kellygirl, I just posted a couple photos of me trying on a cropped Bebe jacket in Sarah's thread:

I'm 5'6", but I usually buy petite blouses and jackets because I have weird proportions (long legs/short torso and short arms). In stores like Banana Republic and Ann Taylor, petite tops fit me WAY better.
The Bebe jackets - at least the ones I tried - just came in S,M,L rather than numbered sizes. I often fall between a small and medium in many stores; for the cropped jackets I thought the small was better (on me) because it's supposed to be a tight-fitting look. The photos I posted are of me in a small.
After looking at their size chart, it's consistent with what I'd expect. Based on my bust measurement I should be exactly between a small and a medium.
Sorry, I feel like I'm not explaining myself very well. I hope this is helpful.
