What We Don't Love: They're not seamless, and if you don't get the right size the waistband can dig. Skims makes some of the best shapewear on the market, and that includes the brand’s mid-rise seamless brief. The underwear is designed to be basically invisible under your clothes, while supporting, shaping, and lifting at the same time. Kratky found the seamless underwear to be a great staple underneath her bike shorts at the gym. They're comfortable, stretchy, and don't show from under form-fitting bottoms. While it didn't disturb her, it's worth pointing out that the waistband is on the wider side, so it's not as minimalist as some of the other options here.

Seamless underwear is available in various cuts, ranging from thongs to bikinis to briefs. Each style provides a different amount of coverage and feels different on your body, so think about how much skin you want to show and how supportive you want your underwear to be when considering the cut of your seamless underwear.

These thongs are great for everyday wear and are also the best thongs for working out. You'll get the look you want in an upscale style that works with every outfit, especially your go-to leggings. Cotton: Soft, breathable and absorbent, cotton is a great option for those with sensitive skin. While most underwear today is made with synthetic materials, you might find that they have cotton gussets for comfort. The three most common cuts are full brief, Brazilian and thong. All of these cuts are widely available in high, low or mid-rise styles.

What We Love: This thong is made from cotton, but according to reviewers, it’s not bulky and lays flat. Tracy Freno, customer service manager at lingerie destination Bare Necessities, agrees saying, “Despite what some people may think, thongs are actually very comfortable and are a great undergarment to wear to prevent panty lines under clothing. Most thongs are designed with super soft fabrics like lace or cotton, which are lightweight and gentle on the skin. The right thong panty has the ability to make the wearer forget they are wearing any underwear at all!” An elevated version of the basic brief, this style from Natori features delicate lace trim and a lower waistline for a more feminine flair. Testers gave this pair perfect scores for comfort, highlighting the "buttery soft" and lightweight feel of the material, with one tester raving that she "honestly forgot that they were even there" when wearing them. While testers were skeptical that the lace would feel uncomfy or dig in, they were pleasantly surprised by the smooth and stretchy feel.While cotton might not be the most lavish underwear material, it certainly is the best for protecting your sensitive, intimate areas and preventing irritation and even infection. Though cotton is soft against skin, it’s actually sturdier than other fabrics, more durable and more breathable. Cotton undies can keep their shape better too, as well as provide ultimate comfort and support.

Neutrals and nudes can be great for clothing that’s less opaque than others. (When wearing white pants, you should wear underwear in a color that matches your skin tone.) On the other hand, bright colors and bold patterns can simply feel more fun . Questions You Might Ask What’s the difference between seamless and no-show underwear? While thongs made from specialty fabrics are good for date night, they may not be the best option for daily wear. Thongs intended for daily wear should be made from breathable, comfortable materials. If that means cotton to you, then go for it. If it means modal or a stretchy lace, that’s fine too. According to Freno, “As long as your thong is laundered properly and fits well, they are perfectly safe and hygienic to wear.” That said, it’s also important to wear these items judiciously — keeping things sanitary may include changing them out once or twice a day to prevent the spread of bacteria.

Stretch recovery: Underwear should stretch to conform to your body for the perfect fit, but it's important that it maintains its shape after the elastic has been stretched. We evaluate stretch recovery by marking a section on the underwear, stretching it out and clamping it into place for two hours. We then release the clamps, wait a minute and measure the markings to determine how well the underwear was able to return to its initial shape. After one hour, we remeasure and then score the results. While VPL (visible panty line) isn’t the worst fashion faux pas of all time, it can be quite annoying to deal with when putting together an outfit. In fact, that's what makes seamless underwear such a handy thing to have in your closet—they make it look like you're not wearing undies at all, without sacrificing comfort. Either way, no matter if you like to wear super fitted styles or hyper- compressed leggings during your HIIT sesh, a seamless pair of panties can really be your outfit’s saving grace. If you’re still wondering whether you need thong panties in your drawer or not, here are a few tips on when to wear them and why you need to own at least one pair (just in case!). Whether you want to flaunt your gorgeous booty after all the hours spent at the gym or simply want to wear a bodycon dress - a thong is a must-have. You may look stunning in that body-hugging outfit, but the panty lines spoil the whole experience. This is the perfect time to wear a thong! Thongs also go incredibly well with yoga pants, tight skirts, and leggings that require your panties to be as discreet as possible. You can also wear thongs during hot summer days as they offer more breathability compared to other underwear designs.What We Don't Love: The waistband is a little wider, making this not as minimalist as other options. Hipster : Like the bikini, this is a low-rise style that sits on the hips. It has more coverage around the hips with wider panels of fabric. I'm a huge proponent of undergarments in breathable fabrics such as cotton, but if you're still seeing lines or your ensemble leaves little to the imagination, opt for a seamless thong (usually nylon, jersey, and/or spandex) for a nearly invisible look and feel,” says Blanc. Keep in mind that a loose thong may bunch and lead to an uncomfortable fit, and bunched fabric may be visible under your clothing. On the other hand, thongs that are too tight can feel restricting and lead to chafing, which is equally uncomfortable. Wearing a thong that fits perfectly and provides you with the comfort you deserve will leave you feeling empowered and give you the confidence to take charge of your day,” says Freno. “[For that reason], sizing is important to think about when buying thongs. [Ultimately], if the panty is too small, it will create an unattractive look and uncomfortable feel.”
