Women's knickers are the foundation of any outfit, and while girls might spend plenty of time selecting the right bra to match, they often overlook their undergarments. Then there are the little things, like the stray cat hairs that might be hiding in their black panties or the thread coming loose on a favorite pair of socks. That's why we tapped the Good Housekeeping Institute Textiles Lab and gynecologist-approved brands to find the best women's pants and panties. Whether you're looking for seamless underwear with no VPL (visible pubic line) or an invisible brief with added shapewear, we've got you covered. We also sourced styles made of plant-based fabrics and other unique materials that make for seriously soft, comfortable and sustainable underwear, including merino wool (which is eco-friendly when it's produced using closed-loop processes) and Tencel. From thongs to Brazilian briefs, there's no shortage of options in this category, which we call "panties" in the USA and "knickers" in the UK. These form-fitting undergarments, which are usually a bit longer than today's briefs, were popular from the 18th to 19th centuries and are sometimes called drawers, knickerbockers or smalls. It was around this time that the corset's popularity began to wane and hemlines started to get shorter, which led to undergarments getting even smaller in size. These bottoms graze your navel and provide medium coverage. They're a great option for everyday wear and work well under high-waisted jeans and skirts. women's knickers
