Verywell / Chloe Jeong If you have a closet brimming with leggings, you know the struggle of finding complementary underwear to go along with form-fitting activewear. A comfortable pair of underwear that provides a smooth (and preferably invisible) look depends on proper fit and seamless construction. You can find no-show underwear in thong, cheeky, boy short or classic styles to suit all your needs. Fit is one of the most important features because bunching or pinching will cause them to show through your leggings. Look for bonded or laser-cut seams and soft fabric to banish visible panty lines. We reviewed underwear for leggings based on style, material, type of seams and tags, and affordability. A certified yoga instructor from our Review Board also reviewed this article for accuracy and the best ways to evaluate underwear for leggings. Here are the best underwear for leggings that'll create a VPL-free look. Verywell Fit FYI Recent news has suggested a PFAS concern surrounding Thinx products—some of which are included in our list of recommendations. Thinx has agreed to settle a lawsuit claiming its products contain short chain per-and polyfluoroalkyl substances (PFAS), and Agion anti-microbial treatment, but the brand denies the allegations. PFAS, also known as toxic “forever chemicals,” have been linked to several health issues including various cancers, liver and thyroid diseases, and more. We spoke with experts to learn more about PFAS and what this settlement means for consumers. You can learn more in our "Frequently Asked Questions" section below.

What to Look for in Underwear for Leggings Style Underwear styles, and even workout underwear, range from maximum coverage cuts to barely-there fashions. There are options in every category that can provide a smooth foundation under leggings, free of pesky panty lines. Thongs: These cheekless panties provide the least coverage with an open back. The lack of fabric eliminates VPL. Cheeky: Striking a balance between a thong and a brief, cheeky underwear flaunts some cheek without totally sacrificing coverage. You can even opt for a high-rise cheeky style for a little extra tummy support, like the OFFLINE No Show High Waisted Cheeky Legging Underwear by Aerie (view at American Eagle Outfitters). Boyshorts: For those who aren't a fan of thongs but want a panty line-free caboose, a boyshort can provide the same effect, since the fabric doesn’t stop at the cheek. These booty shorts come just over the buttocks into a short-short style for a seamless, smooth look. Classic Styles: For those who desire a classic underwear cut, choose a combination of the desired cheek coverage and rise for the perfect fit. Popular styles include bikini, hipster, brief, and high-cut brief. Fit When underwear is too tight, you guessed it, it creates panty lines—especially when styles incorporate elastic. Nobody likes the feeling or look of undies digging into their skin. On the other hand, if underwear is too loose, it can ride up and cause the fabric to bunch or wrinkle, which can show through your leggings. Seams and Tags Rough, raised seams are not only uncomfortable but can be unflattering. To avoid chafing and visible panty lines, look for seamless underwear with bonded or laser-cut seams for a no-show, invisible look under leggings. Always go tagless—not just for the sake of vanity, but for comfort. Nobody likes the feeling of an itchy, rubbing tag on their bum. Avoid extra lines and added discomfort with a tag-free pair of underwear. Material Just as you would when picking the best shoes for walking on ice or the more appropriate running jacket, selecting the right underwear material is key. Cotton and sweat-wicking materials are your best bet for sweaty endeavors. You can even find a combination of the two, with a sweat-wicking body and a cotton crotch. If you have sensitive skin down south, natural breathable cotton is the best option. Just be sure to bring a dry pair for after your workout. Personal trainer and Pilates teacher Alexa Idama prefers wearing a cotton thong under leggings. “Cotton thongs are breathable, fit well, and tend not to overstretch like some of the other thongs on the market,” she said. “They are also the least visible under my workout pants and fit well over my thighs without sagging around my waist.” For high-intensity workouts, quick-drying underwear made from sweat-wicking fabrics helps wick moisture away from the body, rather than absorbing it and making you feel damp. This helps you stay dry and comfortable. Sweat-wicking performance fabrics are a popular choice under leggings since the tight nature of activewear makes you more susceptible to sweat down under. For the closest thing to feeling like you’re wearing nothing, choose an ultra-thin, sweat-wicking fabric that molds to the body for a wrinkle- and ride-up free fit. Frequently Asked Questions Is it ok to not wear underwear with leggings? Yes, research shows it’s ok to skip wearing underwear with leggings. In fact, for those who dare to go bare, many styles of leggings feature a gusset—a triangular piece of fabric sewn into the crotch—which acts almost like a built-in pair of underwear that absorbs moisture.Just as some people prefer cropped leggings and others prefer full-length, what you wear underneath is a personal preference. For both pro-panty people and fans of going commando, the rules are the same. Bacteria and yeast thrive in dark, moist environments—whether one goes bare or layers up.Opt for breathable and sweat-wicking materials—whether choosing underwear or going straight for leggings sans underwear. What happens if you don’t change your underwear after working out? Lingering around in damp, sweaty clothes is a bad idea. By doing so, you become susceptible to a slew of bacterial and fungal infections—not to mention body odor—including a yeast infection, clogged pores, acne, chafing, and skin irritations. At a minimum, always pack a spare pair of underwear. Should I be concerned about PFAS? Short chain per-and polyfluoroalkyl substances (PFAS), also known as toxic "forever chemicals," are most often used to make products non-stick, grease-resistant, and waterproof. "They are likely used in period underwear to provide a waterproof barrier between the underwear and the skin," says Kelly Johnson-Arbor, MD, FACEP, FUHM, FACMT, Medical Toxicologist, Co-Medical Director, and Interim Executive Director of the National Capital Poison Center.PFAS have been linked to several health issues including various cancers, liver and thyroid diseases, and more. But these synthetic chemicals are commonly found within the environment and our bodies, says Johnson-Arbor.While Thinx denies the allegations, they settled a class-action lawsuit that claims their products contain PFAS. Thinx consumers grew concerned about the impact of these chemicals in the brands period underwear. But after speaking with OBGYNS, physicians, and researchers, our team made an informed decision to keep Thinx in our final list of recommendations. We're exposed to PFAS on a daily basis, according to experts, so using period underwear for several days every month may not pose additional health risks."People are exposed to PFAS daily in the air we breathe, the water we drink, and the food we eat. It's impossible for us to avoid PFAS exposure in our daily lives. We don't need to be alarmed about the potential for health effects due to the use of Thinx products," says Johnson-Arbor.
