What makes a plus-size kneesuit different from a regular swimsuit?

A kneesuit offers longer leg coverage and a more streamlined fit, ideal for fitness swimming and modesty. Ours are specially designed for curvy and tall body shapes that need extra length and support.

Are your plus-size kneesuits suitable for competitive swimming?

Definitely. While they’re stylish enough for leisure, our kneesuits are made with performance fabrics that resist chlorine and salt, hold their shape, and stay comfortable in training or racing lanes. They don't have a FINA stamp, but they compress enough for low level competition events.

What if I’m unsure about sizing?

Kneesuits usually run smaller. If you’re unsure, we suggest sizing up 1–2 sizes. You can also message us for personalised advice.

How fast is delivery and can I return if it doesn’t fit?

We ship quickly across the UK and internationally. If your kneesuit isn’t the right fit, you can return it as long as the swimsuit is unused.

Do your kneesuits help with body confidence?

Yes! Many customers tell us they feel more confident because the suits are fully lined, supportive, and don’t ride up. The knee-length cut also provides extra comfort for women who prefer more coverage.

Care for Your Kneesuit

Extend the life of your swimsuit with simple care: rinse in fresh water after swimming, hand-wash with mild detergent, avoid wringing, and dry flat in the shade. This protects the chlorine-resistant Lycra® and keeps your kneesuit in top condition for seasons of swimming.
