Girls' Swimsuits & Swimwear

Of course! At decathlon.com.gr you will find a wide variety of kids' swimsuits for girls, specifically designed to offer maximum comfort, stability, and high durability during pool training. The collection includes classic one-piece swimsuits with an athletic back (Y or X shape) that ensure complete freedom of movement in the water. Most of our models are manufactured with Aquaresist technology, offering excellent resistance to damage from pool chlorine so they retain their shape and colors for a long time. Their soft and elastic materials fit the body perfectly, allowing young swimmers to focus exclusively on their performance. For a complete look during lessons, you can pair the swimsuit with appropriate swim caps & goggles that ensure comfort and protection on every lap.

For swimming lessons in the pool, the right kids' swimsuit for girls must primarily offer stability and freedom of movement, though the style depends on each child's needs. The classic athletic one-piece swimsuit with a Y or X-shaped back remains the most popular choice, as it hugs the body evenly and does not slip during intense training. However, an excellent alternative is a one-piece swimsuit with built-in shorts (legsuit) or a two-piece athletic swimsuit (top with shorts), which offer greater coverage and absolute confidence. Additionally, for winter training or pools with cooler water, thermal swimsuits are available, which keep the child's body warm, preventing shivering during the lesson. Don't forget to consider Aquaresist technology for maximum chlorine resistance for your final selection. The correct fit will allow the child to focus on the lesson, whether she is learning her first strokes using kickboards and swimming learning aids, or doing advanced training. To complete her preparation, don't forget to organize her backpack. A practical swim bag with waterproof compartments will keep dry clothes protected from the wet swimsuit, while a pair of non-slip pool slippers is essential for her protection and hygiene in the locker rooms.

Yes, if your child spends hours under the sun, the best choice from the girls' swimsuit collection is a one-piece with UPF 50+ certification. These swimsuits block 98% of UV rays, offering permanent protection that does not degrade with washing. At decathlon.com.gr you will find one-piece sun protection swimsuits with short or long sleeves and a back zipper, which fully cover sensitive areas like the shoulders, as well as legsuit-style one-pieces (with built-in shorts) that stand out because they offer extended UV coverage on both the torso and thighs. The latter are the perfect "hybrid" option for girls who want maximum UPF 50+ protection without sacrificing the freedom of movement offered by a classic athletic garment.

To find the ideal size in a kids' swimsuit for girls, the golden rule is to base it on the child's height and actual measurements rather than exclusively on her age, as every body grows at its own pace. At decathlon.com.gr, every product page features a detailed size guide. To be absolutely sure, you can use a tape measure to measure the child's height, chest circumference, and waist. Especially for pool training, the swimsuit should have a snug and "full" fit on the body without cutting into the shoulders. If the swimsuit creases or sags, it means it is too big, which will allow water to enter while swimming and make it difficult for the child. However, if your child is between two sizes, opt for the larger one if it is a one-piece sun protection suit with sleeves, but stick to the smaller one if you are looking for a classic athletic training swimsuit that needs to stay stable. Once you find the right size, next up is choosing a pool bathrobe and your little one is ready for the pool!

A girl can wear a one-piece swimsuit from the very first months of her life, usually from 3 to 6 months old, which is when she starts her first baby swimming lessons. For very young ages (up to 2 years old), one-piece swimsuits are designed with soft, elastic materials that make changing swim diapers easy. As the child grows and transitions to independent learning (from 3-4 years old and up), the classic athletic one-piece becomes the most essential piece for the lesson, since it offers the stability needed for her first strokes. At decathlon.com.gr you will find appropriate kids' swimsuits for girls that cover every developmental stage, from the first infant contact with water to teenage training. For those first steps in the pool or the sea, you can pair the swimsuit with kids' armbands & pool rings that provide the necessary buoyancy and safety. Meanwhile, to protect sensitive young skin from sun rays at outdoor pools, an excellent addition is UPF 50+ certified sun hats, which complete your little one's protection under the sun.
