AQ/AQ Backless Satin Dress

Beautifully structured backless satin dress by AQ/AQ. In mint condition w/ tags still attached. I purchased this from another posher, but it turns out that my hips are too wide for the dress :( I would definitely go by the measurements in the size chart. AQ/AQ might call their UK 6 a US 2, but to me this seems like a US 0. I usually wear a 26 or a 2, and like I said, I could barely get this over my hips.
