For a no-frills, classic option, check out these soft cotton undies from Subset (formerly known as Knickey). One Glamour tester says these plus size-friendly cotton panties are great for buying in bulk (a pack of three costs $50, instead of $20 a pair) and loves the variety to mix and match. There are a ton of different silhouettes—from low-rise thongs to mid-rise bikini styles—to high-rise briefs and come in a range of colors. Our testers appreciates the fact that you can buy these with or without a leg elastic, too. The brand remains big on sustainability and recycling, and accepts all kinds of underwear, bras, socks, and tights (kids too!) which it uses for new materials like insulation, carpet padding, and furniture batting in exchange for $15 in-store credit.
