...okay, here goes, since my surgery, my "girls' are quite a bit smaller and more "perky". i made an appointment at macys', you can go to any good quality department store, macys', hudsons, goldwaters' von maur, dillards ect. call the lingerie section and there is always some slightly older female who can and will do the proper fitting. make an appointment. she will measure under your breasts against your rib cage, comfortably snug, not tight enough to make 'overhang' anywhere. then over the nipples the difference in inches is the cup size. she'll get two or 3 styles, wireless, racer back (strap angled towards the center not straight up and down)or what ever type you want to try on. when you find one that you like fit and it feels good on you and (this is important....) it looks good under the snuggish white tshirt that you bring with you, you'll be able to find a good supportive bra. i got one to wash and one to wear. i like lands end ones, they hold up well to machine washing, but line drying, the fabric feels soft against my skin and the prices, especially on the saturday overstock sale days are very good. the support comes from the band and the cups, and in my case the underwires. the support is not from the shoulder strap,( trench shoulder hurts. ) and some mammography centers, mine does, have bra fitters on staff as well. women who have had mastectomies or reconstruction for whatever reason (surgery or burns for example) can be also served. when you know your correct size, you can buy properly fitted and well supportive bras that will make your clothes look better and make your shoulders and neck hurt much less. the prices are still a bite tho', so i go on line to search out the extra ones when i know the model number and size of the bali i like.
