Sizing WAY off

The suit is nicely made, double lined, well stitched. Colors are nice. That being said, I looked at the sizing chart- and picked the correct size from Decathlon’s own chart. It’s WAY off. My daughter wears a 7/8. I bought a 10 as dictated by the 52”-54” (also following the guidelines saying they run small). Their 10 is WAY to small! Also extremely thin cut! I will try to return for a 14 I guess. The size 10 fits my 3 year old perfect! She is average high and weighs only 32lbs and wears a size 3 normally. Their size 10 is not to big on her??!!!

Great quality too small

Great quality. The the sizing is way way off. Way too small.

Way too small

I bought the biggest size for my daughter which corresponds to her height, but there is no way she can fit into it. Unfortunately this is already the largest size in this style. Will be seeking a refund on this one. We've been really happy with Decathlon swimwear sizing until now, and the design is lovely.


This suit was way to small in length and width. My daughter fits size 10 at most other retailers. Your size guide does not offer sizing information for girls swimwear either. Refunding is $8 and the suit cost me $12. I'm better off donating it. Not sure I'd buy from you again simply because of the refund cost. Make refunds simpler and we'll talk

sizing problem

Very nice swimming costume but it comes in really small size. My daughter is 11, average high and I had to return the size 12 and 14 now. I'm giving up.

Half the size

There is no way the sizes of the swimming costumes are correct. They are about a third of the size they should be!!!!! its like they are for 5 year olds with a 14yr old label on

The size of the swimsuit was too small.

Tiny swimsuit

I wish I'd read the reviews before buying this, I normally do. I bought an age 10 for my 7 year old as she's tall for her age. When I took it out the bag I couldn't believe how small it was. I actually thought I'd ordered a swimsuit for a 10 month old instead and checked my order, no joke! This is cheap for a reason! What a waste of money. I'll give it a one star for being a nice colour but there is no point even trying to get my child into this. What a disappointment.

way way way too small!!!

So disappointed with this item. I know the clothes at Decathlon are known to be small but this is ridiculous. I bought the size 12 for my 7 year old daughter and it was way too small. The cost to send this back is almost as much as the item itself so there is no point sending it back either so complete waste of money.

Way too small!

As the title says, I bought this for my daughter and found it way too small. We ended up buying a suit 4 times bigger than her age (she is average height and weight for her age) and then it was still too tight and barely covered her chest.

Good product. Fitted well.

Inaccurate sizing.

Bought this in an age 10 for a very slim 8-year old. Sizes on label corresponded to her measurements but she can't get it over her shoulders. I previously bought an 8-year size when she was 6, but am surprised she will need a 12. I think the company needs to re-visit sizing procedures.

Additional Product Information


Main fabric

  • 82% Polyester cationic
  • 18% Spandex


  • 100% Polyamide

Your practice

Beginners swim: young beginner swimmers who are starting to swim and need ease and comfort. For her, Nabaiji offers a wide range of swimwear that allow her to swim with products suited to swimming, but that also meet anatomical requirements


Y-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 Y-shaped closed back swimsuit is ideal if you have a larger bust.


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.

Score to compare the environmental impact of products

The environmental impact of the product is calculated over its entire lifecycle and with different indicators. An overall score (ABCDE) is attributed to help you easily identify the products with the best environmental performance by comparing products of the same type with one another (T-shirts, pants, backpacks, etc.). Decathlon chose to apply this voluntary environmental labeling system. For more information, visit:
