At G cup, the right swimwear choice comes down to one thing: encapsulation. Styles that separate and support each side of the bust independently — rather than compressing everything across — give far better shape, comfort, and hold in and out of the water.
That's exactly what bra-sized swimwear is built to do. Elomi Swim is our most reliable pick at G cup and above — their wide underwires and deep, projected cups are engineered for larger busts. Panache Swim offers similar structure with slightly narrower wires, which works well for petite frames at a larger cup.
Fit notes for G cup
Side support panels make a significant difference at this size — they stop the bust migrating outward under the arm when you're active. Adjustable straps are worth prioritising too; a small difference in strap length has a big effect on how the cup sits. If you're unsure between styles, our team fits G cup every day and can point you toward the right cut for your shape.
