Designer Children's Swimwear Inspiration For Summer 21

by Team Kathryns 21 May 2021

It’s been difficult to plan for a summer getaway, but with travel opening up as lockdown measures ease, we can all start to look forward to some summer sun. So, whether you are planning to jet off to Portugal or simply enjoy watching your children splash in the paddling pool, a new swimsuit is an essential addition to any child’s summer wardrobe.

We’ve rounded up our favourite picks of the coolest children’s swimwear from designer brands including Monnalisa, Sal & Pimento and Boss, to help you with designer children’s swimwear inspiration as the weather warms up!

Board shorts for boys

For your little surfer dude, a pair of stylish board shorts is a must-have for hitting the beach.  These Boss swimming shorts have an all-over HB print, with handy side pockets and an elasticated waist with a drawstring for the ultimate in comfort and a great fit.

All children love to wear vibrant colours, so dressing them in these bright red Lanvin swim shorts will keep them happy – and the pop of primary colour also makes little ones very easy to spot on the beach.

For sunny days at the lido, we love these citrus trunks from Sal & Pimenta, featuring fruity lemons on a blue and striped background. They are a shorter length and have a yellow drawstring waist that is easily adjustable.

From sun-drenched beaches to swimming lengths at the local pool – our new season collection of boys swim shorts has styles to suit kids of all ages, from beach babies to uber-cool teens.

Sweet swimwear for girls

What could be sweeter than a strawberry-print swimming costume for your little girl?  This all-in-one frilled swimsuit from Monnalisa is fully lined and has a clasp back fastening for comfort.  Finished with ric-rac braiding and coordinating stripe detail, this swimsuit can also be teamed with a matching sarong skirt with a frilled asymmetric hem for summer 2021 style.

Keeping your little ones safe in the sun is incredibly important – but if you’ve ever tried applying sun lotion to a child who just wants to jump in the pool, you’ll know it’s not an easy task. Billieblush has come to the rescue with a delightful dolphin print long-sleeved swimsuit that has anti-UV properties. It’s sold with a cute striped plastic pocket bag, so your mini fashionista will look stylish while staying safe in the sun.

Best swimwear for beach babies

The youngest members of the family will look super-cute in this baby girls flower hooded poncho designed by Phi Clothing.  The snuggly material is ideal for drying off at the beach (or for cuddles after bath time).
