Once the top is on, it's fabulous. My complaint is that it's difficult to get in. I had a hard time shuffling the shirt over my chest in a size medium. The shirt's fabric does not have a lot of give and it's designed to hug your curves. I'd definitely try this on before buying to see if you can get both in and out of this shirt.
I am wearing this top now and it is very cute. It is thin for summer and literally flows when you walk. I wear a black cardigan over it while in the office and it still looks cute. The shirt is really long, it goes past my butt and I am 5.5". I purchased my usual medium. If I went smaller, it probably would have been too difficult to get on and off. My only complaint is that the back is so low, that you can see a bra. This defeats the purpose of having a cute cut-out in the back. If the cut-out were a little higher, then it could hide a bra. Overall, LOVE the top. Very feminine.
