This is a size medium from Rampage, new with tags. It's basically a halter top, with some lace, and it shows a lot of cleavage. It would fit anywhere from a medium to a large. I'm a 38D and it fit fine. $5 plus shipping.
This is from Victoria's Secret. It's a size 38D strapless bra. I bought it thinking I would need it, but never wore it, because I don't like feeling like it could fall down. No straps included. $10 plus shipping.
