pink training bra

I have had this since I was a teenager and dug it out of storage. Don't know where my mom got it. Appears to have two layers of fabric on top of the breast area but no actual cups or underwire. Does cover your nipples though. Buttons all work; straps and band size is unadjusteable. I washed it in the washing machine for years with no problems. No stains. Doesn't list a size but it's just a little too small for me, who has a underbust of 31" and a bust of 36". Band size of 27" and stretchy.
