There are specially adapted sports bras for such activities as yoga and pilates, so that you only have to wear the bra layer and not overheat.
Wear racerback bras for racerback tops. Like the halter bra, the racerback bra has straps that mimic the shape of the top that shares its name.
Choose a color that matches your top or stick with a neutral color.
If your breasts brim over the cup in the middle or at the sides, the bra is too small. If the bra fabric is pinched together in places and not filled in by flesh, the bra is too large.
