No-Show Seamless Underwear for Everyday Leggings
I used to layer dark leggings over whatever I grabbed from the drawer and pray nobody noticed. These are the pairs that actually disappeared under fabric, even in lighter colors.
Grab these if you want something cheap that genuinely works. I wore them under gray leggings to a meeting and saw zero lines in every bathroom mirror check.

George Women's Thongs 6-Pack
Bonded-Edge Underwear That Won't Leave Lines
Seamless gets all the attention, but bonded edges are the real secret. No stitching along the leg openings means nothing to press through stretchy fabric.
Use these under pencil skirts too, not just leggings. A coworker asked if I was going commando because she couldn't spot a single line. That's the review right there.
Jockey Women's No Panty Line Promise Tactel
Pricier per pair, but I've had mine for over a year and the edges haven't curled or frayed. Worth it if you're tired of replacing cheap ones every few months.

The name is silly but the fit is serious. The wide waistband sits right below my belly button without rolling down, even during a long car ride.

Moisture-Wicking Underwear for Gym Leggings
Wearing cotton underwear to the gym under compression leggings was my mistake for years. The dampness, the bunching, the regret. These fixed all of that.
Try these before your next long run. I wore them through a humid 5-miler and they dried so fast I almost forgot I'd been sweating.

Snag a pack before your gym bag runs out of clean options. They weigh almost nothing and dry between washes faster than anything else I own.

Customer reviews for (5 Pack) Reebok Women's Stretch
Use these for hot yoga specifically. I used to bring a change of underwear post-class. Now I don't need to because these handle the sweat without getting gross.
Champion Women's Hipster Underwear, 3 pack, Sizes S
Ditch your cotton pairs for these on cardio days. The material is slick enough that leggings glide over them instead of grabbing and creating lines.
Justice Girls Seamless Bikini Undies, 5-Pack, Sizes 6-16
Underwear That Stays in Place During All-Day Wear
Riding up by noon was my biggest complaint with most pairs. I'd be in the office doing the secret tug and hoping nobody noticed. These actually stayed where I put them at 7am.
Wear these on days you're sitting for 8 hours straight. I wore them through two back-to-back flights and never once had to adjust. Not once.

Try a pack if you run hot and hate that sticky feeling by afternoon. The mesh keeps air moving and the cut stays exactly where you place it all day.

Thongs That Are Actually Comfortable Under Leggings
I resisted thongs for years because every pair I tried felt like a punishment. Then I found ones that made me wonder what took so long.
Wear this if you've always said thongs aren't for you. It's so light I genuinely checked twice to make sure I put it on. Disappears under everything.

Splurge on a few of these. I bought one to test and immediately ordered four more. The fabric is like a second skin and the waistband doesn't roll.

Get this if you want a thong that smooths your lower belly area too. It's slightly higher rise with gentle compression. Flattering without being shapewear.

Swap your current thongs for these and do a legging test in the mirror. I did and immediately donated every pair that showed lines. These won.
Secret Treasures Women's thong panties, 3 pack
High-Waisted Underwear That Pairs With High-Rise Leggings
Nothing ruins a good high-waisted legging like underwear that peeks out the top or creates a muffin line. These match the rise so everything looks clean.
Wear these with any legging that sits at or above your belly button. The waistband blends right in and doesn't create that double-band look.
Blissful Benefits No Muffin Top Panties
Grab a few in nude shades. I wore them under cream-colored high-rise leggings and my reflection showed absolutely nothing. Just smooth fabric.

Use this when you want a tiny bit of hold without committing to full shapewear. It smooths just enough and the high cut matches high-rise leggings perfectly.

Kindly Yours Women's Seamless Bikini Underwear
Best Nude and Color-Matched Underwear for Light Leggings
Dark leggings forgive a lot. But the second I started wearing lighter shades, I realized most of my underwear drawer was a liability. Color matching changed everything.
Get your actual skin-tone match. I'm medium-toned and this shade disappeared completely under oatmeal-colored leggings. Like wearing nothing but with coverage.
Calvin Klein Women's 3 Invisibles Hipster Panty
Try this shade if you have a deeper skin tone. Most brands only make one nude and call it universal. This one actually matches and actually vanishes.
Jockey Women's No Panty Line Promise Bikini - 3 Pack
Pair with pastel leggings. I wore these under lavender and blush pink and saw nothing in photos. The color is neutral enough to work under almost any light shade.
Hanes Originals Women's Seamless Rib Bikini Underwear
Wear this when you're doing something where people might see your silhouette, like outdoor workouts in sunlight. The ultra-thin fabric casts no shadow at all.
Bali One Smooth U All-Around Smoothing Hipster Panty
Snag this if you've ever had a VPL moment in a photo and cringed. The transparency is about the fabric weight, not see-through. It just melts into your skin tone.

Use this shade under tan or camel leggings. I tested it under those viral butter-soft leggings and the mirror confirmed zero lines from every angle.
