Calvin Klein Bralette / US M

Calvin Klein grey triangle bralette with classic hook closure in back. Unpadded but does have slits to add padding to the cups. Adjustable straps, elastic band. Bought as a medium, but does not have tags. I would estimate it fits like a 32B. Band measures 25.5” end to end. Bust measures 4.75” top by strap to top of band.
