Shocking sizing

Bought this bikini for my 9yr old, she is by no means a big girl, very slim & slight infact. I purchased the age 10 & the sizing is ridiculous! This made her feel self concious and she commented that she was "fat".. no 9yr old should be thinking those things about themselves let alone saying them! My 5yr old neice tried this age 10 bikini on & still it looked a bit too small. This is absolutely ridiculous, dissapointed is an understatement! Do not purchase this product & if you do id suggest you add on 4/5 years to the age you actually need. Shocking!

Dear Leanne,

Thank you for your feedback. We are sorry to hear about this situation. In most of the cases the size up or two should be OK. However sizing is a very individual matter and we can only advise about the size (age in this case). All swimwear should be tried before first swim. This is also why we provide 365 days return policy to make sure all of our customers can find best fitting size, whether purchased online or in store.

This particular model is still created using the previous size template used in the company, but from Spring 2020 we will begin to receive our new range of childrens swimwear, with more up date market sizing trends.

Please do not hesitate to return this swimsuit to your local or use the online procedure for full refund or exchange.

Once again apologies for any inconvenience caused.

Kind regards,

Kornel - Water Sports Commercial Leader

Sizes you have to guess at

My 7 year old daughter needed a swimsuit for our holiday so I brought one of these. I ended up buying a 12 yrs size but to be honest it is a bit tight so should have brought the 14 yrs. I know sizes differ but these are ridiculous.

Kids swimwear

I bought a size 8 for my 7 year old and a size 10 for my 9 year old. The sizes are way out very small and had to be sent back. They are so small that the size 10 was still too small for my 7 year old. A real shame as the costumes were nice but the sizing is shockingly bad

Additional Product Information


Main fabric

  • 82% Polyester cationic
  • 18% Spandex


  • 100% Polyamide


  • 80% Polyamide
  • 20% Spandex

Your activities

Swimming for beginners: young beginner swimmers who are starting to swim and need ease and comfort. For her, NABAIJI offers a wide range of swimwear allowing her to swim with products that are suited to her and in accordance with her anatomical requirements


X-shaped back: a swimming swimsuit should focus above all on comfort, to allow you to perform your movements with ease, without discomfort or pain. That is why it is important to choose the cut of the back of your swimsuit carefully. In X-shaped back swimwear, crossed straps allow good freedom of movement. As the straps are not fixed together, they adapt to all body types.


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 restriction

Not recommended for use on slides.
