Good for 30 mins swim lessons for 4 year child.

Bought a size 12 for my soon-to-be 11 year old but what arrived was more suitable for a 6 year old. A shame because the style and design are really nice.

Basic swimming costume

Okay for the price. Very thin in quality so can’t imagine will last log with regular swimming. Nice look and nice colour to trim in detailing too. Good value.

Excellent costume

I bought this costume over the years in many sizes for my growing daughters. It is a brilliant swimsuit, I can highly recommend.

Poor quality and completely wrong sizing

Size 14 years old is so small that it looks to me like a size 8 years old. No lining, completely see through. Really poor quality. Won't be buying any items from this brand in the future.


Bought Age 12 for my average sized 11 year old. The swimsuit has come and is tiny. The reviews showed 4.5 starts out of 5 so I didn't check individual comments before buying, but now I see that they are all saying that the sizing is very small with some commenting that their 7/8/9/ year olds are wearing the Age 14 costume. If the 14 yr old costume fits an 8 years old then label it as Age 8 and stop wasting people's time!!!!

Nice fit & quality

My daughter looks nice in it. Please note though that sizes do come up small. My daughter is 6 - this was way to small so we got a size 8 which fits perfectly

Dear Meena,

Thank you for your recent feedback. We are sorry to hear that our swimsuit become way too small for your grand daughter. We are working on different solutions to make our swimwear sizes more up to date with the current market trends. Currently we recommend to go 2 sizes up compare to the child age but of course this is an individual aspect of each user. Please visit your local store or use the online procedure for full refund or exchange.
Once again apologies for any inconvenience caused.
Kind regards,    


I ordered age 6 the swim suit is no where near an age 6 it would probably only just fit a 2 yrs old. I haven’t returned the item as it’s more hassle than it’s worth and I don’t live near to a store I won’t order again

Extremely small sizing!

Lovely product, wearing well, only downside is the crazy sizing. My daughter is 7 & average size for her age. She’s ended up with this costume in age 14! Unfortunately this also means she probably won’t be able to get the next size costume at Decathlon. Such a shame. Sort it out Decathlon! In theory I should be able to buy her kids costumes at your store for the next 7 years but as the sizing is so appalling it looks like I’m going to have to shop else where. Can’t imag how much of your business must involve returns due to this issue.

Your activities

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.
