I'm 5'3, 130 lbs., 34 B, ordered a medium.

I wanted to like this since it had such great reviews, but...eh. The "organic cotton" is thick and stretchy, which is okay, but it's not why I bought it so I'm pretty neutral on thatm My 2 major problems are the length and straps. The cami is a bit short, I really REALLY hate it when cami's roll up from being too short. I have to pull it down periodically to adjust. The straps are very thick and very uncomfortable. The rough threading only makes it worse. It makes the cami feel heavy and bulky. I use it when I don't want to wear a wire bra (mainly workouts) but I wouldn't sleep in it -- not comfortable enough.
