We are officially in fall, where it’s not quite cold enough to comfortably wear a puffer jacket but not middle of the summer heat (for the most part) — which means humidity that comes with surprise rain showers, and swampiness from layers, along with the heightened possibility of, ahem, nether-region irritation. While you should always wear what you want to wear down there, the “best” underwear, friends, is tried-and-true cotton — and that’s why we’ve been on a mission to find the best cotton underwear for women and people with uteruses.
