I hear ladies talk a lot about how they do not feel or look sexy when going to the gym or jogging on the street. Complaints on breasts jiggling are also commonplace.
Dressing to go to the gym or to jog on the street is like dressing to the red carpet, you are supposed to be cautious about everything you put on.
Sportswear can be fashionable too
Take note of your sports bra; From the left you have the A-B cup size compression sports bra, the C-cup or larger encapsulated natural shaping sports bra, the C- through D or larger compression/encapsulated sports bra. Pick out the one that best suits you.
Either of those sports bra, will keep you comfortable and keep your breast in check and make you look sexy too.
