Grey/Silver Zac Posen structured corset blazer!

This blazer features 4 clasps in the front is made from mostly acetate spandex and nylon so It is quite heavy but stretches. The lining is silver polyester. There is a mini fishtail back and bell sleeves. While most of my listed clothes are in excellent condition (worn once), I have worn this a few times and am willing to negotiate on price.
