Fuller-Cup One-Piece Swimsuits
Supportive one-pieces for fuller busts
Discover fuller-cup one-piece swimsuits designed for lift, comfort, and a naturally sculpted shape. Our DD+ friendly styles use hidden power mesh, wider straps, and smart seaming to keep you secure—so you can swim, lounge, and move with confidence.
Styles that fit and flatter

Adjustable straps (multiway or halter) to fine-tune support across shoulders and back.

Moulded or removable cups with bust darts for a smooth, rounded profile.

Power-mesh lining at the bust and waist for gentle hold without stiffness.
-
High-leg or classic cuts to choose your preferred rise and bottom coverage.
How to pick your perfect fit
Start with your usual bra band and sister sizes, then adjust straps until the bust panel sits flat—no gaping, no spillover. If you’re between sizes, choose the larger for length and use the straps to customise support.
Fabric, care & longevity
Soft, resilient stretch blends keep their shape in salt and chlorine. Rinse after each swim, hand-wash in cool water, and dry flat out of direct sun to maintain colour and elasticity.

What makes a one-piece ‘fuller-cup’ supportive?
Fuller-cup one-pieces combine deeper bust panels, wider adjustable straps, power-mesh lining and moulded or removable cups to lift and secure a fuller bust without wiring.
How should a fuller-cup one-piece fit at the bust?
The neckline should lie flat against the chest with no gaping or spillage. Adjust straps so the bust is supported and the under-bust seam sits comfortably without digging in.
Which leg line and coverage should I choose?
High-leg cuts lengthen the legs and feel modern; classic legs provide more seat coverage. Pick the rise that matches your comfort and planned activity.
Will the fabric stretch out over time?
Quality elastane keeps its recovery when you rinse after wear and hand-wash in cool water. Avoid harsh detergents and prolonged sun-drying to preserve fit and colour.
Can I wear a fuller-cup one-piece for laps and beach days?
Yes. Look for adjustable straps and power-mesh for movement support, then choose your preferred leg height and coverage for comfort from pool to beach.
