Black and white semi formal dress

I am selling a great condition cocktail dress in a size 7. It fits around a size medium. The dress is strapless and stays on well. There are three little black buttons on the top, as well as a slip underneath that has a few inches of tulle to give the bottom of the dress some shape. If you require more pictures or measurements (provided on Poshmark only, not through private email), please let me know. cheers
