This dress is a real show stopper. I wore it to three different black tie/formal weddings and it was a huge hit. It is a halter that ties in the back. Back is cut fairly low. Bought it new for $3500. There is a small tear in the chiffon on the very bottom from dancing (side note - this dress moves beautifully on the dance floor!). The measurements (European sizes) are 40 170/92A. This corresponds to a size M/8, chest size 90-94 cm, waist size 78-82 cm and neckline 37 cm. I am usually a size 8 and the dress fit perfectly, although since it is meant to be a looser fit, if you are a size 6 it would likely fit well.
