Disappointed customer

It looks very good but the sizing it way out. I purchased a size bigger as I often need to do a quick change. Unlike the Mary Yuka (same UK size) I purchased at the same time this was at least one size smaller than I would normally purchase i.e. at least two sizes smaller than that stated. It is smaller than the one I purchased in my normal size. It creates bulges where they should not be any and feels as if the stitching on the back will not last long as it was tight on the hips. I was so pleased with the Yuka that I removed the labels before trying on and as there is not a store near me returning would have been difficult.

Your activities: gentle aquafitness

Aquafitness activities are a great way to combine relaxation at the pool and the benefits of sport. The risks of injury associated with aquafitness are minimal. Gentle aquafitness offers relaxing activities and light strength training. Aquafitness is performed upright: during exercises, you should feel well-supported. This is why Nabaiji swimsuits offer you various bust support solutions.

Bust support

Preformed built-in cups: For aquafitness sessions, it is preferable to choose a swimsuit ensuring good bust support. The preformed cups have a rounded shape that gives a uniform, rounded appearance to your bust. In addition to giving support, they also add an aesthetic advantage.


Body-sculpting material: Our body-sculpting swimsuits use fabrics with a special kind of mesh structure and a high percentage of spandex (30%) to guarantee a highly elasticated fabric. Your swimsuit has a body-sculpting effect: as soon as you slip it on, you'll feel well-supported and comfortable, without it compressing your body.

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 with different indicators. An overall score (ABCDE) is attributed to help you easily identify the products with the best environmental performance. Compare products of the same type with one another (T-shirts, pants, backpacks, etc.). Decathlon chose to apply this voluntary environmental labeling system. Website: Explanatory video:
