Great fit and feels great

Not a maternity swimsuit

Collected order today and it's just a normal swimming costume. I'm a size 10 but 25 weeks pregnant so needed bump room - have ended up buying size xl!

Great fit, ok material

I'm 5'7", size 12 and 19 weeks pregnant and ordered a medium which fits really well. It seems there is lots of give in the rouched material around the middle for my bump to grow. There's an elastic panel under the bust which is comfortable and not too tight and is supportive enough for my growing bust, and the material doesnt pull down like some costumes! The only downside to this costume is the material is not as good and quick drying as more expensive costumes (like Zoggs or Speedo), but for the price I wouldnt have expected it to be.

Fits well

I'm 5'6" and this swimming costume fits well, neither pulling up or down which can often be the case with these things when combining a large bust and long body, never mind a bump as well. Material stays put where it should do, although I did find myself 'tucking myself in' a little around the bust area as there's not a lot of support there. Plenty of room for a growing bump...I wore from about 32 weeks to 37 weeks.

Good quality, nice and comfortable. I'm so happy of this product !!!

Great value, comfortable and attractive design

I'm 31 weeks pregnant, tall at 5'9" and was worried I wouldn't find a maternity swimsuit to fit me. I ordered this online, in my usual size and I have been so pleased with the product. It looks good and fits so comfortably around my bump.

Producto de calidad media

Sirve para salir del paso en caso de tener que ir a la piscina, lo rocé con cuidado al aclararlo tras la natación y enseguida algunas zonas se deterioraron. El modelo queda bien, cubre bastante, pero esperaba un poquito más de calidad.

Additional Product Information


Main fabric

  • 80% Polyamide
  • 20% Spandex


  • 100% Polyamide

Your practice level

Beginner's swimwear made for beginner swimmers who are starting to swim and need ease and comfort. For those primarily looking for a water-related physical activity, for the well-being and health benefits. Nabaiji offers a wide range of swimwear that allow you to exercise with products suited to swimming but that also meet anatomical requirements.


U-shaped back: above all, a swimsuit should focus on comfort to allow you to move with complete freedom, without restriction or pain. That is why it is important to choose the cut of the back of your swimsuit carefully. A scoop back makes it easy to put on and avoids tan lines on your back if you swim outdoors. Ideal for larger sizes as it is easy to put on once over the hips.


Material: 80% polyamide / 20% spandex. Chlorinated water can be harmful to swimsuits that are used repeatedly in swimming pools. The spandex fiber that gives the material its stretch and therefore makes it comfortable, also becomes fragile when in contact with chlorine. If you swim occasionally, this material will be fine for you. If you swim regularly or intensively, opt for a 100% polyester material.

Use restrictions

Not recommended for use on slides.
