K Cup Bras

K Cup Bras That Raise The Bar (And Your Bust)

If you wear a K cup, you’ve likely spent years adjusting straps, doubling up on layers, or settling for something that just “does the job.” It’s time for better. Rose & Thorne bras aren’t just sized up from “standard”, they’re built specifically for larger busts, with stability, comfort, and confidence at the forefront. From our plus size bras and K cup sports bras, to our wirefree and underwired range, you’ll never have to sacrifice style for substance again. 

K Cup Size Bras Are Engineered For Support

Every wired K cup bra we make is part of our Premium Support range. These styles are built with an upright underwire that brings breast tissue forward, helping to reduce strain and improve shape. Higher-cut cups allow for extra coverage, helping prevent spillage and eliminating that “monoboob” feeling. The straps, seams, and underband are all designed to spread weight evenly and stay comfortable through long days, movement, and whatever else is on your plate.

How To Choose A K Size Bra 

At K cup size, you know exactly what you need from a bra, and what you won’t put up with. You need deep cups that scoop and support, a strong band, wide straps and a centre panel that sits flush. Australian bras from Rose & Thorne do all that and more, with comfortable 24mm wide straps that support without digging into your shoulders, and a wide band with a 3-hook closure (4-hook on sizes 22K and 24K).
