The bikini is one of the more basic underwear patterns, or as Victoria’s Secret says “the under thing for everything.” In the bikini panty, your cheeks have just the right amount of coverage, which adds to their classic appeal. As Rygorsky explains, “A bikini wearer isn’t easily swayed by the latest craze.”

Just don’t get classic confused with boring. While the bikini panty is great for lounging around the house (can you say comfy?), the bikini wearer is “usually an outdoorsy and/or athletic type,” says Calhoun. It must be their utilitarian nature. Zip line across the Amazon, or go for a neighborhood run — we bet your undies won’t need any adjustment along the way.
