Pilates has become one of the fastest-growing fitness trends in the UK. From reformer studios to matching activewear sets, women are investing in quality leggings, grippy socks and stylish workout outfits that carry them from studio to coffee shop. But there's one thing many Pilates girls are still overlooking – their underwear.
The Best Pilates Outfit Starts with the Right Underwear
The perfect Pilates outfit isn't just about flattering leggings – it's about what you wear underneath them. Many women spend £80 or more on premium leggings, only to wear underwear that creates visible lines, feels uncomfortable or doesn't breathe during class. If you're looking for the best underwear for Pilates, comfort and invisibility should be top priorities.
Why Your Underwear Matters During Pilates
Unlike high-impact workouts, Pilates involves slow, controlled movement, stretching and positions where you're constantly bending, rolling and moving through different ranges of motion. The last thing you want is:
- Visible underwear lines
- Underwear that bunches up
- Thick seams showing through leggings
- Fabric that feels hot during class
- Constantly adjusting between exercises
Good underwear should be something you never have to think about.
Meet Collection No. 2
Our answer is Collection No. 2 – a seamless-look 100% cotton G-string designed to disappear under your favourite Pilates leggings. No visible lines, no bulky seams, just a smooth silhouette that lets your activewear do the talking. Most seamless styles lean on synthetic microfibre to get that smooth line; ours gets there with 100% cotton instead, so it works as genuine no VPL underwear without giving up breathability. Because if you've invested in beautiful leggings, why spoil the look with underwear lines?
Why Cotton Makes the Difference
Many seamless underwear styles rely heavily on synthetic fabrics. At Cotton Coup, we've taken a different approach – our cotton-rich design combines the smooth look you want under leggings with the breathable comfort natural fibres provide. That means a softer feel against your skin and better breathability, whether you're flowing through reformer Pilates, heading to brunch or spending the rest of the day on the go.
Pilates Isn't Just a Workout – It's a Lifestyle
Part of why Pilates has exploded in popularity is how seamlessly it fits into everyday life. Most women don't head home to change after class – they grab a coffee, run errands, work remotely, meet friends. Your underwear needs to be comfortable long after your workout ends.

If you're searching for the best underwear for Pilates, here's what to look for:
