XL Briefs That Fit Beautifully and Feel Even Better
If you’ve ever been told that your size means fewer choices, we’re here to tell you it’s time to stop compromising. Our XL women’s underwear come in the same flattering styles and comfortable fabrics as the rest of our range, because great knickers shouldn’t stop at a certain size.
Need help finding the right fit? Our knicker size guide is a good place to start.
Women’s Xtra Large Undies Should Support, Not Squeeze
Sick of wasting your valuable time searching for quality XL briefs in Australia? Ours are thoughtfully designed with real bodies in mind - no scratchy seams, awkward cuts, or settling for “close enough.” Just genuinely supportive, ultra-comfortable women’s underwear that works with your curves.
All our styles are available in women’s XL (though fair warning, some do sell out fast). Want all-over comfort? Try our Full Briefs. After a little shaping support? Our Cotton Control Briefs are always a favourite. Prefer a barely-there feel? Head to our XL G-Strings.
And if you’re after a full set, take a peek at our bras for the perfect match.
