The assistance I received in store from the friendly staff was fabulous. As someone who hasn't worn anything but bralettes and crop tops for the past number of years I had no idea what my size would be. But the girl that was assisting me look one look at me and guessed my size. The first one she picked was a little on the tight side, so we just went up one cup size and it was then perfect. It was a super efficient and non-judgemental experience :)
