F Cup Swimwear

F cup is the sweet spot where great swimwear design starts to get genuinely interesting. You have enough projection to need real structure, and enough choice at this size to be selective.

Support that actually works

At F cup, underwired tops are worth prioritising over soft-cup styles. A proper underwire sits flat against the chest wall, lifts from below, and keeps the cup shape intact when you're moving in water. Brands like Freya Swim and Panache Swim build their swimwear using the same cup construction as their bras — which means the fit logic is already dialled in for your size.

Style without compromise

F cup doesn't mean full-coverage-or-nothing. Elomi Swim does plunge bikini tops in sizes up to K cup. Curvy Kate offers adjustable-strap styles in bold prints. If you want a one-piece, look for structured cups with adjustable or removable straps — they give you far more flexibility in fit across the shoulders and bust.

Our full F cup swim range runs from size 8 to 20 across bikini tops, one-pieces, and tankinis. All bra-sized, all fitted for projection and shape — not just volume.
