I ran to the store to try to this on after seeing it online. i'm usually between a small and medium on tops depending on the shirt; the 6 fit true to size. everything about this shirt fit perfectly and it is beautifully designed, but it is just soooo sheer. i had a nude bra on and you could see every detail of it through both the front and back. i couldn't wear this comfortably without a cami. disappointing as i had the highest hopes for finding a crisp white shirt for the summer!
