I ordered this dress for my 11 year old daughter (5ft 2in and 90lbs). I ordered a size 10 as her measurements corresponded to that size. We loved it. but he has a tie so you'll never know). She wanted something on the floor for a concert with an orchestra. It had to be all black and finding something that was her size, age appropriate and not easy was a challenge. This is very hard. Beautiful dress, nice material, well cut, it's comfortable, the price corresponds to the quality.
