My bra is are making a gap in my front, should I be concerned?

If you are concerned. About how your bra is fitting would encourage you to go in person to a specialty bra store. Up to 85% of american women are wearing incorrect bra size. The professionals at a specialty bra store can ensure that you have the correct band and cup size as well the best design to fit your need. You will also be taught how to properly settle your breasts into the bra. It is worth the effort.
