People will wonder if you’re even wearing anything at all 😏

Skims

Ah yes, seamless underwear. The MVP of the lingerie drawer – working day and night to prevent that dreaded visible panty line, or VPL, as most folks like to call it. Like a good strapless bra, seamless underwear opens up a whole world of fashion that would have otherwise been a no-no without going commando.

But while we’re all for ‘no pants’ for those who feel comfortable doing so, sometimes it’s just nice to have that extra bit of coverage and support from a seam-free design. Better yet, many also have a ‘second-skin’ feel, so you’ll forget they’re even there at all.

If you think seamless underwear only refers to standard skin-tone thongs, though, just you wait. There are sooooo many different options in a variety of colours ready to satisfy your every knicker need. Think: thongs, briefs, hipsters, shorts, bodysuits, shapewear, exercise underwear, sexy knickers, period panties... It’s all possible seam-free and sans VPL.

Ready to bid farewell to pesky panty lines ruining those killer outfits you took days to put together in your head? Scroll on for our picks of the best seamless underwear, knickers, and thongs available.
