A crisp pair of white pants mixes up the monotony of denim and dark neutral chinos and slacks. Unfortunately, your look can be quickly marred by the wrong pair of underwear. From visible panty lines to see-through pants showing your undergarments, white pants present a number of problems when you pair them with the wrong underwear.

Wearing the wrong underwear can reveal more than you intend — and show off your favorite hot-pink thong to everyone you pass.

Guys can wear white pants too, whether you’re rocking a pair of white denim on the weekends, a classic pair of white chinos on a first date or breezy white linen pants on a tropical getaway. Your underwear must be chosen thoughtfully.
