18K Bras

Bras in Size 18K, But Better

If you wear an 18K bra, chances are you’ve spent years making do. Sister sizing, wishful thinking, and endless trial and error. And even when you do find your size, the options are usually uncomfortable, bulky, or just plain ugly. That’s why so many New Zealand women love Rose & Thorne plus size bras. Every style in size 18K is designed to support heavier, denser busts without turning getting dressed into a full-body workout. The fit is firm, but flexible. The lift is impressive, but natural. And best of all, they’re so cute you’ll actually want to wear them.

Size 18K Bras Are Anything But Basic

At any size, you deserve quality underwear, but at 18K, it’s a non-negotiable. Our size 18K bras come under our Premium Support range, where every aspect has been designed with you in mind. Our bras feature a smoothing 3-hook underband, extra-wide straps that distribute weight evenly, and our specialised ‘C’-shaped wire that brings breast tissue forward while reducing side spillage. A higher-cut cup helps keep everything contained and comfortably lifted, giving great shape and support.

How to Choose the Best 18K Bra

At 18K bra size, full cup styles are your best friend. Look for deep cups with strong side panels that hold their shape. Our 18 K bra size range includes almost every colour under the sun, so you’ll have as much choice as ‘standard’ sizes. Whether you’re looking for staple everyday bras like our black or nude bras, or a lacy red or multi-colour design, you can shop for what you like, not what’s left. And, thanks to our Forgiving Fit technology, if your size changes a little, you won’t have to shop for a whole new collection.
