XL G Strings That Don’t Make You Compromise

If you’re a size 18–20, you’ll know that most g-strings aren’t made with your body in mind. Too short through the rise, too narrow on the hips, they roll, pinch, and never sit quite right. Ours are different. Rose & Thorne XL g strings are cut specifically for size 18–20 proportions, with soft fabrics, thoughtful seams, and a shape that stays put. Flattering, comfortable, and the best pick when you want to avoid panty lines.


XL Undies for 18–20

Looking for more than g strings? We’ve got you. Our extra-large knicker range includes bikini briefs, midis, and full briefs that won’t ride up or dig in. You can even shop our plus size lingerie sets and plus size underwear to get everything sorted at once. Chasing a bargain? Our lingerie sale is always worth a scroll.


Why You'll Want an XL G String on Hand

These are the undies you’ll reach for when you want your outfit to shine, not your seams. That slinky skirt? G string. High-waisted trousers that show every line? G string. Long day ahead and no time for constant adjusting? Definitely g string. Designed for Australian bodies, our XL thongs and g strings work with your clothes, not against them.
