("wifebeaters"). Why? I'm 25 and reasonably fit (5'10" & 160 lbs.) and dress conservatively - oxford button-downs, lace-up shoes, etc. - for my job in finance. Underneath I wear what's most comfortable to me. I notice all kinds of underwear on the other younger guys in the locker room, though I guess boxer-briefs with or without regular t-shirts dominate. I find both too confining. Why the kidding over my shorts & shirt? I'm not sure how much I care. Maybe my undies aren't considered cool for some reason. Any thoughts?
