Good value

Nice flattering costume for the price, but be aware of sizing, I am always a 10 to 12 UK size but had to go to the equivalent of a 14, EU size 42

Great swimsuit with build-in pad

Lovely swimsuit, decathlon seems to be the only one offering build in pad and I have had a few swimsuit from them. Order a size bigger as they run small but is a very flattering costume. Highly recommend.

Great swimsuit - good quality, not thin. Fluorescent coral back stripes look cool!

Worst costume ver bought

I chose this as I wanted a padded cup and I decided a sports shop would offer the best quality for every day swimming. Firstly, the size is tight and uncomfortable (as mentioned in other post). But the worst part of this costume is the padding. They are not secured so move as soon as the swimsuit is washed. It is almost impossible to reposition them as there is the tiniest slit on each side to get your finger in. It takes me at least 5 minutes to put this costume on and readjust it! Terrible... I will never buy swimwear from decathlon again!!


Good quality , comfortable

Lovely swimsuit

Having read other reviews I ordered a size up, but really didn't need to as it's quite loose. I'd be exchanging for the smaller size if they weren't out of stock.

Definitely size up!

As a full size 14 I opted for the 16/EU 46, although the paper stitched on size label describes the size as a 20??? Fits perfectly and looks great. High cut legs but not obscene and boobs held well intact so not at all boobilicious. Black and pink option is beautiful as there are little gold highlights all over it which don’t come across in the images.

Swimming cozie

Fits really we and washing ok the I've taken the pads out the boob bit due to it frusting when wash you have to stick your hand in to.move them about so gets little frustrating

Can only echo others comments- I went a size up and it was unbelievably tight, dug in everywhere, especially the back. Shame as it looked like it would be nice.

Very good

Very good quality

Your practice

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


X-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. In X-shaped back swimwear, cross 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.

Restrictions of use

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. Explanatory video:
