Size 4. Worn for my bachelorette dinner. Excellent preowned condition. One small loose strand on the front and small spot on the mesh boning that is not noticeable. 100% silk. Needs to be steamed to keep the bow from falling down. Perfect for weddings, bachelorette, or even just a nice evening out! Has a double zipper, one for the mesh interior and then the back zipper making it very secure. No longer fits me! Make an offer!
