XL Underwear That Feels as Good as It Fits

We’re here for the girls who’ve been told their size means limited options. Spoiler alert - it doesn’t! Our womens XL briefs come in the same styles, fabrics and fits as the rest of our range, because great knickers shouldn’t stop at a certain size. 

Need help picking a style? Start with our knicker size guide.

 

XL Briefs Designed to Fit Real Bodies

Finding quality XL underwear in New Zealand shouldn’t be a mission. Our ultra large briefs for curvy bums are made with comfort, shape, and support in mind. No awkward seams, no settling for “close enough.” Just knickers that work with your body, not against it.

All our styles are available in women’s XL underwear sizing (although some sell out quicker than others). Want the confidence of full coverage? Explore our Full Briefs range. Looking for a little shape? Try our Cotton Control Briefs. Want to keep it minimal? Our XL thongs are right this way. 

And if you’re after a full set, take a peek at our bras for the perfect match.


Why Kiwi Women Love Rose & Thorne XL Knickers

  • Real sizing, real comfort. Not scaled up from smaller cuts, our XL briefs are made-to-fit, not stretched-to-fit.

  • Every style, every size. You’ll find the same cuts, colours and fabrics available in XL as you would in smaller sizes, because you shouldn’t have to miss out.

  • Built-in confidence. Our XL briefs are soft, secure, and shaped to feel good all day. No digging, sagging, or second-guessing.

  • No “nana” vibes. Just knickers that fit, flatter, and feel like you.


You know what feels good. You know what works. Now you just need more of it in your drawer. We’re ready when you are.
