What to look for
Fit is Key
A poorly fitting swimsuit will cause chafing, restrict movement, and generally make swimming uncomfortable. Ensure you allow enough room for a full range of motion – you should be able to comfortably extend your arms and legs without feeling constricted. Consider the cut: racerbacks are good for backstroke, while square-leg suits offer more freedom for freestyle.
Fabric Matters
Chlorine is incredibly damaging to swimsuit fabrics, causing them to break down and lose their shape. Look for suits made from chlorine-resistant materials like polyester or blends with spandex. Consider the thickness of the fabric – thicker fabrics offer more support and durability but can also be less breathable.
Style for Your Stroke
The style of your swimsuit can affect how efficiently you swim. For example, a full-coverage suit offers greater buoyancy and warmth, which might be beneficial for open water swimming or cooler temperatures. However, it can also restrict movement during faster strokes.
First Time Buyer Mistakes
Many first-time buyers focus solely on aesthetics, neglecting the importance of fit and fabric. It's common to buy a suit that looks great but doesn't perform well or is uncomfortable. Don't be afraid to try several different styles and sizes to find what works best for you.
Choosing the right swimwear is an investment in your swimming experience. Prioritise fit, fabric, and functionality to ensure comfort, performance, and confidence in the water.
How we chose
Picks are drawn from the swimwear we track on Amazon UK, selected by the rule described under each heading above — not a fixed list of products, so a pick can never quietly point at something out of stock. Where we say a product is well-reviewed, that reflects verified Amazon customer ratings and review counts, not in-house testing we haven't done. Prices and availability are refreshed at build time; see the price accuracy page for how recently.
