I am 28 and a bigger girl and I have never had luck with bras. I dont know my exact size but I know my band is a 44 according to measurements. I cant get a reliable cup size measurement because I have very top heavy breasts and they dont sit in bras the right way to get accurate bra size. No matter what bra I try the back band always rides up after only a few steps of walking. And no its not because my band is loose as I have had bands so tight they make it hard to breathe and they all ride up the same. The current band I have is a 40 which is two sizes smaller than my measurements and its on the smallest clasp and still roles up the same. I cant have wire bras as again my breasts are very top heavy and they just pull the bra down and bend the wire down making them fall out. Are there any actual full coverage bras that will keep in breasts that cant sit in bras the traditional way?
