These aren’t your backup pairs. These are the ones that make you do a double-take in the mirror. Our XXXL briefs are designed for size 24–26, with flattering cuts, soft stretch, and a whole lot of “damn, I look good” energy. Because style doesn’t stop at a certain size, and your underwear shouldn’t either.  Need a size check? Our knicker size guide makes it easy.

 

XXXL Undies That Go Beyond Comfort or Control

Let’s be honest, when you’re shopping for plus-sized briefs, you usually get two options: soft and shapeless, or tight and unforgiving. We do the basics, but better - cotton control when you want hold, full briefs when you want something cosy - and a whole lot more too. Try our thongs if you want to skip the VPL. Or prints if you’re done with beige. With Rose & Thorne, you’ll find a whole range of styles that don’t apologise for your size, or your standards.

 

The Benefits of Our XXXL Underwear

  • Made to fit, not just stretch. Our XXXL briefs are designed for sizes 24–26, with shaping and fabric that moves with you.

  • More than just beige basics. Every colour and print you can imagine, because curves deserve options too. 

  • Flattering, not frustrating. No more briefs that bunch, dig, or disappear halfway through the day.

  • Confidence built in. The knickers you feel so good wearing, you wouldn’t mind showing them off!

 

You know what feels good. You know what works. Now you just need more of it in your drawer. Ready when you are.
