Summer chambray!
I love this top!! i got lucky and found it returned at a store (always always check the "found and collected racks ladies!) it was a 6 and i was a little worried it would be much to large, but it fit great! i like that i can wear something under it or on its own. i didn't fit it too short, but i'm a little under 5'7" and roughly 127 lbs, 32/34a. highly recommend!
