Size XL Thongs & G-Strings

XL Thongs That Don’t Make You Compromise

If you’re a size 18-20, you already know that thongs don’t always get made with your body in mind. Too short in the rise, too narrow in the hip, they roll, pinch, and sit in the wrong place. Ours are different. Rose & Thorne XL thongs and g strings are cut for size 18–20 proportions, with soft fabric, thoughtful seams, and a shape that stays put. They’re flattering, comfy, and a trusted option when you want to avoid panty lines.

Why You'll Want an XL G String on Hand

Long day ahead, and you don’t want to be adjusting your briefs every five minutes? Yep, g string. Made for NZ bodies, these XL thongs work with your clothes, not against them.
