32 34 A B cup MP Activewear Women Sports Jog Gym Swim Workout Exercise Top-Bra

I see no tag/tagless info on its size.

Its armpit to armpit is 12" relaxed and stretches with my arms and fists to 17" max/snug making it a 32" 34" (max) Small to Medium, or a Small Medium.

 

As for the cups a S to a M fit.

In overall very good condition.
