This bra measures 29.5" plus a little stretch in band. came in a bag that said 3X but I didn't find it to fit that way.  Therefore I'm selling it here. It was my first time trying this brand of bra. Color is bright white. If 3X is your size and this fits you, I also have a pink one you may want to buy.  This bra brand doesn't have any size or brand tags. I suppose it's made this way. I never wore this bra. Comes from a smoke free home.
