Corset size 2X by SKIMS with lace trim throughout, and unpadded cups. The underwire and see-through mesh lining at the bust, sides, and back. New with tags, I have this corset in every color, but I never ended up wearing this one! To note, I typically run a size L or XL and have a fuller bust, but decided to size up for comfort per personal preference and I am glad I did.
