I stopped running in bra tops + showing my midriff when I got into my mid-40s. But if I could, I would run naked because I don't like clothing flapping all over the place when I train. My racerback tanks are inspired by NBA tanks with all the little holes in them. Slip one of these on + you feel like you are running naked. Designed to be body-skimming + slightly A-line to flatter a woman's curves. Order a size up if you like a looser fit. Layer over your favorite sports bra + go.
