XXL Briefs That Don’t Hold Back

Bigger buts deserve better cuts, and that’s exactly what you’ll find at Rose & Thorne. Our XXL underwear is made to fit properly, feel good, and give you options that aren’t frumpy, flimsy, or only available in beige. Because style doesn’t stop at size 18, and neither should your underwear.

Need help finding your match? Our knicker size guide makes it easy.


XXL Knickers For Girls With Curves 

Your size shouldn’t limit your choices. From smoothing support to feel-good everyday faves, our XXL undies come in all the cuts you actually want to wear. From full briefs, midi and bikini cuts, to purple briefs, print briefs, and everything in between - stock up your stash with stylish knickers you’ll want to show off.

 

Kiwi Women Love Our XXL Underwear

  • Proper sizing, not guesswork. Our XXL knickers are made to fit a size 18–20 body, not just stretched from a size 12 pattern.

  • Bigger bums beyond beige. Brights, prints, comfy or contouring - we’ve got them all, in your size.

  • Support without compromise. Our knickers are designed to stay put, move with you, and hold their shape, wear after wear.

  • Curves deserve options. From everyday basics to fun pieces you’ll want to show off, these undies are made to make you feel good.

 

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