These 26 Pairs of Underwear Look Invisible With Leggings
I often get ready for the gym as early as 5 a.m., so I'm sometimes running out the door with less than two brain cells up and running. If I don't properly plan my outfit the night before, I occasionally end up wearing underwear that isn't seamless, and the embarrassment can hit hard when I'm doing bench squats in a room where it feels like there's a spotlight on me.
To avoid this unfortunate occurrence, I've been on a mission to find the perfect pair of underwear to wear with leggings. As someone who wears leggings daily, I just can't stand the look of visible panty lines. I've tried countless seamless styles, but a lot of them let me down. I recently stumbled upon a game-changing pair of underwear that actually looks invisible when paired with leggings, so allow me to share.

It's the perfect solution for anyone who wants to wear leggings without worrying about visible panty lines.

Customer Review: "With all panties I order one size up. I am a size 4-6 but I always order the medium. The bum is usually a bit larger in the back than you think. That said, these are perfect fit, so light weight and comfortable. If you are looking for a control top spanx product this might not be for you. These are all about the seamless look."
Black is my favorite underwear color, so as you can imagine, I'm in love.
Sizes: XS-XL
Materials: 71% cotton, 29% elastane
Customer Review: "The cotton bikinis are so comfortable I hardly know I’m wearing them. With never a VPL, these have quickly become my everyday staple that I can confidently wear with any outfit. The fabric is easy to care for and holds up well over time. Definitely worth the price point."

Customer Review: "I discovered these last year and purchased 3 pairs, they are the best briefs I have ever had. My dresser drawer is filled with very expensive briefs that I never wear because they are so uncomfortable, roll down etc. I just ordered 9 pair and sent my sister in Maryland 9 pair for her birthday. I will never put another kind on my body again. If you are looking for something that feels like you are wearing nothing....these are a must have."
Wacoal knows a thing or two about making high-quality bras, so I trust its no-show panties.

Customer Review: "These Wacoal briefs are the best. As the name says, they are smooth and seamless. They also are well-made and don't cut or creep up in back."

Customer Review: "This thong is a dream — totally seamless, super soft, and disappears under everything. The Champagne color is perfect for light leggings or white pants, and it stays in place all day without digging in or rolling. Easily the most comfortable and flattering underwear I own. I’m already ordering more!"

Customer Review: "Easy to wear and care for; no riding up or bunching; seems invisible under clothes. This is underwear for grown-ups who want to look good and will pay a bit more for comfort. No real special care needed—a real bonus."
It doesn't get much softer than Hanro.
Sizes: XS-XL
Materials: 95% polyamide, 5% elastane
Customer Review: "These are my favorite! But you do have to launder them carefully (delicate and hang dry). They will pull and lose their smooth/soft finish if you wash on regular and dry."
These might become your new favorite thongs, and lucky for you, they're available on Amazon.
Sizes: XS-XL
Materials: 100% cotton
Customer Review: "These are shockingly light and breathable. I got these for the gym and use cotton underwear everywhere else. These are less obtrusive and flexible, did not trap sweat, and while I would not wear them for daily wear, they seem to be okay for the gym."
Cotton can disappear as well.
Sizes: S-L
Materials: 82% Cotton, 18% Elastane
Customer Review: "The smoothest pair of briefs I have ever worn; I want one in every single color available! Soooo stretchy, fits like a glove, and since it's seamless, I don't have to worry about panty lines or irritation anymore!"
Skims has a reputation for disappearing under your clothes.
Sizes: XXS-4X
Materials: 100% Cotton gussets
Customer Review: "Extremely comfortable, perfect fit as there is no squeezing and not baggy. I was looking to switch to a brand with more cotton content for comfort (especially with my active job) and health and these are perfect."
I'll leave you with a pair that gets incredibly reviews.
Sizes: XS-XXL
Materials: 100% cotton gusset. Body: 46% Cotton, 45% Micro Modal, 9% LYCRA Spandex
Customer Review: "The version of these that I bought had a wider waistband, so I'm hoping this version is just as good. For a long time I've been a fan of the lace-edged cotton VE bikini panties, but as I've aged and my body has changed, I noticed that the lace on the hips was cutting in more, and the front waistband was sitting right on my old c-section scar and bothering it. I decided to give this style a try, and I'm glad I did! Normally hipster panties tend to ride up in the back for me. I had that trouble with the all cotton bikini style, but not with these."
