Some women either don't wear the right size bra, don't know what their breast size is, or even how to measure their breast to determine both..Another thing is how to wash their bra. Now I know your wondering    " Does she think we all are stupid." But I'm serious, don't you hate when your wearing your bra  and the under wire is sticking you? Well if you wash your bra's by hand you can prevent that from happening, also if you want to still wash them in a machine
