Guys Must Avoid These Underwear Mistakes

1. Never emulate K-Fed

Sure, he’s the picture of responsible fathering. By comparison. But tank-top undershirts must never be worn in public as a shirt. Period. They may make you feel like a badass, but in reality you look like a jackass.

2. Go Green or Brown

Putting off doing laundry may make you feel eco-friendly, but remember this: the average pair of dirty underwear contains between 1 to 10 and one full gram of feces, according to Dr. Philip Tierno, director of clinical microbiology at New York University and author of The Secret Life of Germs. Dirty trunks can be ridden with germs. Kill them by washing on high heat, 65 to 70 degrees celsius. Whites can be bleached, another great germ-killer.

3. Tuck Your Undershirt into Your Underwear

Classic Urkel move. Seems like it might keep a blousy undershirt under control, but in fact it causes more billowing, not less. For women, there’s nothing less seductive than an undershirt creating a faux belly—except perhaps No. 2 on this list.

4. Wear Tighty Whiteys if You’re Trying to Procreate

Your boys will produce more sperm if they’re hanging free n easy—cooler temps means higher production.

5. Wear Boxers with Fine Wool Pants

Okay, this isn’t a hard-and-fast rule. Some boxers don’t bunch up when you sit down. But some do—experiment and learn. The classic drape of fine wool pants can be ruined by a lumpy clump of unruly boxer fabric. Briefs or boxer briefs are your best bet with dress pants. They’ll hug your butt and present a smooth appearance to the world. Or at least that part of the world that’s looking at your butt.


6. Wear Cotton Underpants While Working Out

Sure, you can do this in a pinch, but really, it shows a amateurish disregard for performance. And suggests a perverse pleasure in that sopping, saggy feel underneath. Urologists tell us we should wear jockstraps (and cups in contact sports), but the reality is most of us rely on the built-in support of fitness and running shorts. If your shorts have no support, go with a technical fabric brief that wicks moisture away from your body. Even bamboo is preferable to cotton, which soaks up the perspiration.
