Calvin Tran Backless Dress

This dress is a showstopper. I have worn it to at least two weddings and received many enthusiastic compliments every time. I bought this at the Calvin Tran boutique in SoHo, NYC circa 2008-2009. Off the body, the dress is essentially a rectangle of fabric with one diagonal stitch, one arm hole, and three yellow ribbons. It takes some finagling to figure out how to get it on right. There is no fabric tag but it feels kind of like taffeta, possibly a synthetic fabric.
