Size 2 but has built in corset so it can squeeze you in. You're welcome to try on before making purchase. I paid $700 but willing to negotiate on pricing. Dress was specifically made by one prom dress shop so not many out there. I will give you the shoulder scarf and the little purse as well with purchase. Perfect condition and has been sitting in a plastic garment bag. Any questions feel free to message. I'm quick to reply.
