Vintage 80’s 90’s lingerie teddy garter corset

The size of this is listed as a 42. My best guess for today sizing would be a 2X. Lying flat the waist measures 16 1/2 inches Pitt to pit measures 15 inches the total length is 14 inches. This does have a little tiny bit of stretch to it. I am unsure of the cup size, The wire measures 7 1/2 inches from one side to the and cup top to bottom measures 6 1/2 inches. For best fit measure similar well fitting items. Tags lingerie Madonna Victoria’s Secret Hollywood fredericks Christian Dior corset
