is it okay to wear a sports bra in public ie: gym, jogging etc?

[Love22]

i wear a sports bra when working out..normally if i go to the gym i throw a tanktop over it but.... i have a really cute picture i took of myself that i want to post online (its not slutty lol) i'm 23 by the way.... but is it considered tacky or slutty to wear a sports bra and athletic shorts while jogging or at the gym? i havent yet because well i dont know the proper "work out clothes etiquette" and im curious..
