The idea of hiding them in male mode becomes invalid after you reach a certain point. I am a B. A 38B. I have serious east-west issues, so they actually "hide" better than those without east-west trouble. Without anything under a shirt, they are rather obvious to even a casual viewer. I just purchased an under armour men's compression Tshirt 2 sizes too small, to have something to put under business clothing for the occasional situation that calls for no distractions. My older one which was only 1 size too small was no longer doing anything useful. I figured 2 sizes down would solve it. Nope. Guess what? Observers will just have to sort out their distraction issues themselves, without my help anymore. If you think you can hide your puppies once they've grown, think again. They even show through a winter coat because they change your profile. Oh, and lest ye believe women's compression tops work better, that is purest folly. Revel in the 21st century!
