According to our experts, most people typically own at least 30 pairs of underwear to cover approximately two weeks worth of laundry. "I recommend people own underwear in important categories," Fritts said. "Namely, seamless and nude pairs to wear under light dresses and pants, high-waist or control-top pairs for a defined waistline, comfy and breathable pairs for sleeping at night, and, of course, your power pairs that make you feel like a badass for exciting events and dates."
To sum it all up: it's totally OK to throw out old underwear. And, as long as they're properly cared for, it's also fine to save memorable undies for a trip down memory lane. But if you're in need of a refresh, shop some of our favourite brands ahead.
