Seamless underwear is supposed to do one simple thing: disappear.
But anyone who’s worn leggings, a fitted dress, or even their favorite jeans knows the truth, most “seamless” underwear isn’t really seamless. Lines peek through, fabric rolls, or the fit just doesn’t last past lunchtime.
That’s why 2025 is shaping up as the year of innovation in no-show underwear. Here are the best seamless underwear options women are reaching for right now, including our brand-new microfiber line that’s changing the conversation.
1. Love + War Microfiber Thong
Price: ~$34
Why it’s different: Designed to disappear under leggings and slim pants. Smooth microfiber sits flat against the skin with no shifting, digging, or rolling.
Best for: Leggings, yoga, fitted dresses.

Price: ~$38
Why it’s different: A low-rise cut that stays put without cutting in. Microfiber makes it soft enough for everyday wear, invisible enough for body-hugging outfits.

Why it makes the list: Cult-favorite for being literally “invisible” under clothes. The raw edges and lightweight fabric make it a stylist go-to.
Watch out for: Expensive, and some reviews note they don’t last as long as cheaper pairs.
6. Wacoal B-Smooth Seamless Brief
Price: ~$19
Why it makes the list: One of the most comfortable full-coverage options. Soft, stretchy, and available in a wide size range.
