Like choosing the right pen or beer, most guys have a very specific brand and model of skivvies they prefer, and they don’t like experimenting. If you’re buying underwear for yourself, you probably know exactly what you want--although our choices here might be enough to make you think about branching out. If you’re buying for a friend, family member, or spouse, our advice is: Don’t wing it. It’s like giving a man an ugly tie. He’ll feel like he has to wear it, and nobody will be happy.
