Saw this online and had to try it on when i found it in the store. i usually wear an 8 or a 10 depending on how things run, (i'm a 34 dd), so i tried on both sizes. i really could not see much of a difference between the two and was torn as to which size to get. the 10 was just a tad looser so i went with that one, but seriously i could not find or feel much of a difference. it is a very figure flattering top, and a plus that you can machine wash it. simply awesome!
