The Blue Ocean bikini set in these gorgeous shades of blue includes both a top and a bottom that will make any girl feel adorable. The set is part of our Blue Ocean mermaid tail set, but can also easily be used on its own, as a bikini set

The top of the bikini top is equipped with terry fabric that goes down the front. In addition, it gathers nicely around the neck with a tie-knot and gathers pleasantly and naturally at the back under the collarbones with clips. In the end, your girl gets a beautiful look.

The bottom features an adorable mid-rise cut and is double-lined to provide the best comfort and avoid see-through. At the top of the lower part, there is also added elastic to make it fit.

All in all, this is a nice and beautiful bikini set, in which several 1000s of young children already bathe, swim or play mermaid.

Product specifications for the Watery Kids Bikini Top:

  • The bikini top is made of 95% cotton and 5% polyester, which makes the top resistant to chlorine/salt, so it keeps the colour and fit, as well as ensuring a comfortable fit
  • Inside, an extra layer of 100% polyester has been added so that it is not transparent
  • The lock on the back is made of stainless steel
  • It is tied around the neck with the two straps and closed with the clasp on the back. This structure means that you get free movement around the arms

Product Specifications for Watery Kids Bikini Bottom:

  • The bottom is made of 95% cotton and 5% polyester, which makes the top resistant to chlorine/salt, so it keeps the colour and fit, as well as ensuring a comfortable fit
  • Inside, an extra layer of 100% polyester has been added so that, despite the beautiful colours, it is not transparent
  • Has elastic at the top of the bottom, so it fits well up to the waist. Is therefore without laces
  • Is designed with a mid-rise cut, which means it will sit between the hip and navel
  • The bottom is fully lined, which is done to promote comfort

Get the complete Blue Ocean set:

The Blue Ocean set with top and bottom can easily be used by itself as a bikini set. But if your child wants to go all-in on becoming a mermaid, you can find a matching mermaid tail with monofin on this page.

Our mermaid top and bottom set is also available in the colour variants Pink Blush, Sunrise, Milky Way and Rainbow Bloom.

Washing instructions:

  • Wash at 30° or lower
  • Do not put in the tumble dryer
  • Can only be ironed at low heat
  • Preferably do not use highly concentrated chloride-containing detergent
  • Otherwise, the beautiful colours risk fading

The material lasts for a long time. Our top and bottoms will soon become your child's favourite.

Good service and good product

My daughter is happy with her new bikini set, in addition we got a really good service

Susanne R.
Big hit!

However, the top is hard to close for a child, but with a little practice it goes. This is the reason it doesn't get 5 stars :)
