I read another review for this dress that said make sure to get the right fit around the waist as there's no give at the waist. My bust and hip measurements were a 10, but my waist was a 12, so I ordered the 12. When it arrived, it was too big around the bust, so I took it to a tailor. The tailor said the problem was that the strap/upper body of the dress was too long for me, so she took it up at the shoulder. However, she didn't move the built-in cups, or open up the arm hole, so it ended up with the cups sitting above my breasts, and the armhole uncomfortably small.
Of course, none of that is LITB's fault. But next time I order I think I'll get a dress custom-fit or one where the measurements more closely correspond with my own.
