Guys here (Australia) wear those stupid ass loose tanks, that look like they've been in fights and had them stretched. That's about all I can think of.
Honestly, I wouldn't wear 'em unless you're at the gym, home or beach. I'm assuming you want to show off muscles, and quite frankly I (and many women I know) don't find it attractive. Male bodies look amazing in fitted tshirts, where we can see the outline of your body but not the whole thing. leave something to the imagination, bud.
