How Should a 42B Bra Style Fit?

A proper fit is the key to a comfortable bra experience. Your 42B bra should offer ample support while hugging your curves without gapping or pinching. The band should sit comfortably on your ribcage, and the strap should stay on your shoulders without digging in or slipping off.
