My trainer told me that my physique is developing and that I shouldn't be afraid to wear tank tops. So I tried a few. This is my favorite. A neckline that doesn't show too much of the breast. Well adjusted arms (not too much lateral exposure). The fabric is thicker than anything I've tried, but not thick enough to get warm during a workout. Very convenient. I'm not a runner so can't comment on the nipple effects, but for what I do (weight training) it fits well, looks good and is great value for money. I will buy a few more.
