Should I wear sports underwear for non-strenuous exercise?

Some people think, "I never do strenuous exercise, do I need a professional sports bra?" . You may just be standing still for a stretch, but your chest may be overstretched in the process, experts say. Sports bras can avoid the awkwardness of sliding shoulder straps, moving up the steel bracket, and falling out of the buckle caused by strenuous exercise.
