If its a 32B or a 38 B... is there a difference? I know the number is he band around you chest area..but I have big bones there so the band there is naturally going to be bigger than my actual breast cup... so is there a difference? is 38 B a small one?
Yes. the number is the width around your chest. Its like a belt, they come in different sizes to fit around your stomach (your chest in this case). The number is the cup size, the size of your breast. A 38 B would be a larger bra in length compared to a 32B. You don't have to be "fat" in order to wear a larger bra size. If you're just simply built large than you could wear a larger size. In a lot of bra/lingerie stores they are very willing and happy to measure you for free if you need to know. I suggest you do this or try on the bra in the dressing room to make sure its the proper size. Nothing's worse than spending money on a bra that doesn't fit right.
The number is the measurement around the chest just under the breast. The letter is the cub/breast size. So the 32 girl is a slimmer girl while the 38 is not as slim but they both have a similar breast size.
