Vintage corset

Beautiful vintage corset top with sadly cut tags. The material is very good and I bought her from an antique mall from a lady with a stand of burlesque clothing. She told me it was about 30 years old. I love it so much but I lost a lot of weight and it no longer stays up on my chest. The cups are about a b and the waist fits a medium. Of course it is adjustable. The fabric is double lined and the boning is good.
