Our sizes are based on European sizes for ARENA and are marked D in the Size guide below.

Use the charts below to determine your size based on your measurements. The charts below are based on ranges, so look for the range that suits you best. If your measurements indicate different sizes between bodyparts, we recommend choosing the size which most of your measurements fall within. If you are on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit.

For your reference, we have also listed model sizes and measurements on each product page. Please refer to the fit section on each product. We recommend also looking at the description for each product.

Black Arena Shapewear swimsuit for women with Squared Back and delicate Fairy Rose diagonal lines

Arena Isa is a black shaping swimsuit for women who want shaping support, an adjustable fit and comfortable coverage. The delicate Fairy Rose diagonal lines add contrast to the black suit and give it a sporty, feminine look.

Less suitable for

When maximum chlorine resistance and durability are your top priorities. Explore chlorine-resistant swimsuits from the Arena Performance collection.

Shaping and support

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

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.

The same Isa style is also available without C-Cup sizing: Arena Shapewear One-Piece Swimsuit Isa Squared Back - Black

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

Fabric

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. It provides body shaping with LYCRA® Xtra Life™ for enhanced chlorine resistance. The fabric is breathable, quick-drying and rated UPF 50+.

Size guidance

Most women choose their usual size.

Show more Show less

Always compare your measurements with the size chart before choosing. If you can visit the store, we recommend trying the swimsuit on.
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.

Care

Rinse the swimsuit in clean, cold water immediately after use.
Do not leave it wet in a bag or sealed container for long periods.
Hand wash only. Do not machine wash.
Use a detergent suitable for delicate fabrics.
Air dry away from heat sources and direct sunlight.
Do not tumble dry or use a poolside swimsuit spin dryer.
Always follow the care instructions on the label.

Lúdus advice: After swimming in chlorinated water, soak the swimsuit in cold water.

Advice from Lúdus

Chlorine, salt water and sunlight can cause colors to fade over time. Sunscreen can also affect the fabric.
In our experience at Lúdus, light and bright colors tend to show wear sooner than black and dark colors.
White, light and pastel swimsuits may develop a yellowish tint with repeated use in chlorinated water.

Frequently asked questions

Answers to common questions about Arena Shapewear One-Piece Swimsuit Isa Squared Back C-Cup - Black

What size should I choose?

The swimsuit fits true to size and most women choose their usual size. Always compare your measurements with the size chart before choosing. If you are between sizes, the smaller size will generally give a firmer fit, while the larger size will give more room.

How should a shaping swimsuit fit, and will it stay in place in the water?

A shaping swimsuit should feel close-fitting when tried on dry. Swimwear fabric stretches slightly in water and relaxes a little with wear, so a close fit when dry helps the swimsuit stay in place and reduces bagging in the water.

Does the swimsuit have tummy control?

Yes. The swimsuit features Arena's Power Mesh technology, with a Power Mesh panel over the stomach and waist that helps create a smooth midsection and supports a close, shaping fit.

What is the leg cut like?

The swimsuit has a medium cut that provides you with good coverage around the hip area.

Is it suitable for pools and chlorinated water?

Yes. The swimsuit is suitable for regular pool use with proper care. For daily or very frequent pool use where maximum chlorine resistance is the priority, Arena Performance with MaxLife Eco is a better choice.

Is it suitable for water aerobics?

Yes. The swimsuit is well suited for water aerobics and light water exercise. It is designed for support, comfort and shaping rather than a competitive swim fit.

Can I wear it in hot tubs, lagoons and natural hot springs in Iceland?

Yes. You can wear the swimsuit in hot tubs, lagoons and natural hot springs, but rinse it well in clean, cold water after use. Heat, minerals, chlorine and other substances in the water may affect the fabric and color over time.

Can I use it in the sea or salt water?

Yes. You can use the swimsuit in the sea or salt water, but rinse it well in clean, fresh water after use. Salt water may affect the fabric and color over time, as with all swimwear.

Is the fabric recycled?

Yes. The swimsuit is made from Arena Sensitive® Fit fabric with 68% recycled polyamide and 32% elastane.

What does UPF 50+ mean?

UPF 50+ is a measure of UV protection in fabric. It means the fabric provides very high protection against the sun's ultraviolet rays.

How should I wash and care for the swimsuit?

Rinse the swimsuit immediately after use in clean, cold water. Hand wash only, do not machine wash or tumble dry, and air dry away from heat sources. Always follow the care instructions on the garment label.

Will the color fade over time?

All swimwear can show signs of wear over time with exposure to chlorinated water, salt water and sunlight. Light and bright colors usually show wear sooner than black and dark colors.

What is the difference between Arena Shapewear and Arena Performance?

Arena Shapewear focuses on shaping, support, comfort and body confidence for regular swimming, aqua fitness and relaxation. Arena Performance is designed for competitive swimming and regular swim training, where speed, performance and maximum chlorine resistance matter most.
