The different girls’ swimwear styles on offer

Swimming costumes are perhaps the most popular style here, offering optimum comfort and support for your child. Available in a wide variety of styles and colours, as well as leg heights and back types, there’s something for everyone here, with a selection of advanced performance pieces on offer too. Benefitting from high-quality training fabrics, these models combine the strength of polyester with the comfort of spandex - bonus!

A newer style of swimsuit, kneesuits, on the other hand, provide more coverage than traditional swimming costumes, and extend down to just above the knee. Also termed kneeskins, knee-length swimsuits, boylegs and legsuits, to name just a few, they’re ideal for girls who love to enjoy increased freedom of movement in the water.

Finally, we also stock a collection of bikinis, designed for both active and casual use.

Which girls’ swimwear material should I choose?

With so many costume materials to choose from, it can often be difficult to determine what’s best for your child. Certain fibres are designed to last longer in chlorinated water, while others provide a softer and more luxurious feel against the skin. Any swimwear made from PBT or polyester, for instance, is set to last a long time. Sure to keep its colour and shape, much better than Lycra-based alternatives, these pieces are durable, hard-wearing and tough, so highly recommended if your little one swims more than twice a week.

Lycra, otherwise known as Spandex, on the other hand, has been one of the most popular swimsuit materials since the 1980s. Offering better stretch and greater comfort than polyester, it’s always a great fit.
