First Impression

by Kate feat. Lottie (2y 0m)

"You can see the quality right away. I love the colours. Lottie was very excited with her new swimming costume. It runs true to size, we went one size down & it was tight."


The Verdict

by Kate feat. Lottie (2y 0m)

"The design is great, it’d keep all leaks in. It’s great quality & so soft against Lottie’s skin. It dries really quickly which is a plus."

The KIDLY view

"These costumes combine the happy nappy meaning there won't be any leaks while they learn how to swim. Phew."
