Pinup summer dress sheer top

This is a cute pinup dress with a sheer top. The shoulders are sheer. The waist band is fitted. Shorter length. Size says medium. I'd say 4-6 comfortably. I love it but the bust would not work! Threading looks wild on the inside but it came that way. No flaws that I see. 12W 16.5B unstretched 17W stretched bust has about 1 inch of stretch. About 30 in length.
