IAmA professional bra fitter who has fitted sizes 28AA-56KK. AmA
I've worked as a professional bra fitter for 7 years. I've seen about all there is to see concerning breasts. I've fit for women who have had breast augmentations, reductions and mastectomies. I have even fit men for bras. AmA
Edit: I hope my advice has helped the ones that need it. Bottom line is, take the time to find the right size! Find a foundations boutique in your area, if you can. DO NOT put your bra's in the washing machine. Handwash them with Ivory bar soap.
Edit 2: "fitted".... I know it isn't a word. Tequila + typing = cringe
