What sets the Isa apart

Isa is made for regular water activities, comfort and shaping support rather than swim training or racing. The Squared Back gives the swimsuit a clean, structured look, while adjustable straps make it easy to fine-tune the fit. The medium cut offers comfortable coverage, and the C-Cup version is designed for women who need a larger cup size and classic bust support.

The delicate Fairy Rose diagonal lines add contrast to the black suit and give it a sporty, feminine look. At the front, the Power Mesh panel provides tummy control and helps create a smooth midsection.

Fabric, shaping and feel

Isa is made from Arena Sensitive® Fit fabric - 68% recycled polyamide and 32% LYCRA® Xtra Life™ elastane. The fabric is soft, stretchy and designed to shape the contours of the body. LYCRA® Xtra Life™ helps the swimsuit maintain its stretch and shape longer than conventional elastane after repeated use in chlorinated water.

The Power Mesh panel sits at the front over the stomach and waist to help create a smooth midsection and streamline the silhouette.

Fit, support and sizing

Isa has adjustable straps and a medium cut. The cut gives good coverage around the hip area and suits women looking for support and shaping control for a smooth midsection.

Bust support

Classic built-in bra in a C-Cup version with elastic under the bust and lining over the bust. Provides a medium level of support and suits women who want classic bust support in a C-Cup version.

Ludus advice: Based on our experience, the right style and fit often matter more than cup size alone when choosing a shaping swimsuit.

Size guidance

• Based on Ludus experience, Isa fits true to size for most women. Most customers choose their usual size, but always compare your measurements with the size chart before choosing.
• A shaping swimsuit should feel close-fitting when tried on dry. Swimwear fabric stretches slightly in water and relaxes a little with wear. If the swimsuit feels close-fitting when dry, it is less likely to feel loose in the water or lose its close fit over time.
• If your measurements fall between two sizes, the smaller size will generally give a firmer fit, while the larger size will give more room. Use the size chart as your guide and choose based on how you prefer the swimsuit to fit.
