Black Racerback Bra NWOT

Brand new front closure racerback bra. Underwire. Push up. Demi cup. Lace straps. Medium padding. The size tag does say it is a 38D but is too loose for that size. (I wear a 38D in the last set of hooks and this is too loose for me.) There are measurements in the pics. Please compare them to racerback bra of your own to ensure best fit. This could even be a size 42D bra since the band is stretchy. I do not know? Comes from a clean, non-smoking, dog friendly home!
