A wrong size push-up bra means risking inadequate support, the constant need for adjustment, chafing and other discomforts. Getting a push-up bra with the right fit is a little tricky. It can be easy to mistake a proper fit. That’s because they are designed to create more cleavage. This makes it a little harder to figure out if the cups are too small or are the right fit. Remember this to attain the most flattering look.  Go for bras where the cups lay flat against your breast tissue without creating any bulging on the top. The bra should never leave any marks or intends on your breast tissue from wearing it.
