I was so disappointed that my wife didn't fit into these. I bought these a while back trying to figure out what size my wife was in AP Lingerie. I recently had the same trouble with finding her Christian Louboutin Heels. This 100 % Polyamide outfit has silk trim, collar and belt. I want to sell them as the set. The pant waist measures 14" across...I'd assume a 28" waist. Two button straps can adjust it smaller. Beautiful item, new with tags. Robe tag says AP Sm. Pant says Size AP 3, but I believe these run small. All contact thru this site only I will not email you pix or video while I wait for your son to organize payment.
