Shop Kayser lingerie and underwear in size 18. This collection covers everyday knickers in every cut, breathable cotton basics, soft layering camis and special-occasion styles, all designed to fit a size 18 frame beautifully across full brief, hi-cut, bikini, boyleg and Brazilian styles in cotton, microfibre and lace.

The Pure Cotton Hi-Cut Brief is one of the most-loved styles in the size 18 range. Made from 100% cotton with a high-cut leg opening that sits cleanly against the thigh, it is breathable, gentle on skin and comfortable enough to wear every single day without thinking about it. Available in classic everyday colours, it is the kind of brief you stock up on. The Daily Essentials Stretch Lace & Cotton Full Brief (219) is another size 18 staple, combining a cotton gusset with beautiful stretch lace for full coverage and a feminine finish that does not sacrifice comfort for style. For something more special, the Brazilian Babydoll Chemise is available in size 18 and brings a flowy, lace-trimmed silhouette that feels beautiful and generous in its cut. It is the style to reach for on evenings when you want to feel a little extraordinary without anything restrictive or fussy.
