Bra sizes are so annoying. I am wearing a sports bra, back size 32. Today it has been really tight so I measured myself again thinking I must have gained some weight, but I’ve actually lost an inch. I used to be 28 around my ribs but today I am 27. So I didn’t understand why the bra was so tight and I measured it. It is 26 inches, how is that supposed to be a 32 back? I thought if you were 26 around the ribs, you’d be a 30 back, surely a 32 would be far too big. According to my sports bra, apparently not.xx
