Zac Posen size 2 Canary Yellow silk dress - lightly worn

Hi! I got this dress at a sample sale and only wore it once, it is very well fitted and a very canary bright happy yellow! Some of the photos washed out the color. The mid section acts as a corset middle and does not have stretch. It is a silk, chiffon? I will not be fitting in to a size 2 any time soon, so please enjoy her!!
