Do they understand how to measure?
UPDATED 5/3/16: Dresslily.com was very generous in refunding me the money for the ill-designed/fitting swimsuit. As I said, the other products were good, it was just the suit that was an issue. ----- I ordered a beautiful dress that I fell in love with. They had every size available. After a month of "processing", they emailed me saying it couldn't be shipped, and the order was canceled. I was given the option of a refund or store credit with extra points. I took the credit and purchased a necklace, earrings, a pillowcase, and a swimsuit. They all turned out ok except the swimsuit. I ordered a size 2XL as I normally wear a size medium/large shirt, and size large pants - my measurements matched 2XL. The swimsuit is cute, however, this is in NO way a size 2XL. My friend who is a size 6 fits fine. The cups would fit a 36C at the very most, and I'm a D. None of it was worth the money.
