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

Size 14? More like an 8!

Loved the look of this swimsuit & ordered a M (euro 40 / U.K. size 14) as Decathlon advise you to go a size up. I’d say go 3 sizes up!! Decathlon have clearly got their sizing very wrong! I am usually a U.K. 10 - 12 (mostly 10). But not in Decathlon where apparently I’m now a size 16, as the M / 14 / Eur 40 was too small. Really disappointing, especially given the many body image issues in today’s society. No matter what your starting point, adding 3 sizes does nothing for self-confidence or body image! Sorry Decathlon, I will not be buying swimwear from you again until you sort out your sizing.


returned to due to sizing.

Your swimming

The RIANA 1-piece swimsuit is ideal for beginner swimmers.Beginner swimmers who are starting to swim and need ease and comfort. Above all, she is looking for a water-based physical activity for its well-being and health benefits.NABAIJI offers a wide range of swimwear that allow you swim with products not only suited to swimming, but that also meet your body-shape requirements (cover, support, freedom of movement).

The shape of the swimsuit

The RIANA 1-piece swimsuit has an X-shaped back.A swimsuit should focus, above all, on comfort, to allow you to perform your movements with ease, without discomfort or limitations. That is why it is important to choose the shape 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.

The material of the swimsuit

The RIANA 1-piece swimsuit is made of: 80% polyamide / 20% elastane.Chlorinated water can be harmful to swimsuits which are used repeatedly in the swimming pool. The elastane fibre that gives the material its stretch property and therefore makes it comfortable, is also very 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.

Care instructions for the swimsuit

This swimsuit has a built-in bra with removable foam cups, so you can benefit from light chest support while swimming.

Restrictions on use

Not recommended for use on slides.Rinse with clean water after each use.
