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.

An attractive, comfortable & slim-fitting swimsuit

I purchased this swimsuit last month and I've used it a couple of times. I love the style and design as it is brightly coloured and the patterns flatter the female form. It is extremely comfortable and ideal for me as I love to use it both for training and recreation purposes. An added bonus is that since wearing it I've been chatted up a lot at the leisure centre. So I highly recommend this swimsuit to others who are looking for something a bit different. It looks great and feels fantastic. The quality is good as well.

I love Nabaiji!

Nabaiji swimsuit has very good quality and has an affordable price. It fits perfectly for my daughter who is a varsity swimmer and loves the comfort it gives her during training days. We will definitely buy some more.

Swimsuit fit well in me

It make's me feel sexy though I dont have a curvy body. It make's me regain my confidence wearing it.

size matters

the smallest size of most of your swimsuits do not fit my daughter's body. She is training for competitions and she needs swimsuits that she can wear comfortably on every training and as a rule.. swimsuits should be like a second skin to swimmers.. so we have to return the item and exchange it with swimsuits that are meant for 10-11 year olds

не отговаря на снимката

Дизайнът се различава от този на снимката - има една декоративна розова линия, а аз получих с друг дизайн - две декоративни линии и по-различна бяла част на деколтето. Размерът е силно умален - поръчах моя номер, както съветва и таблицата, но реално ми е 2 размера по-малък. Иначе стои добре и изглежда хубаво, но за съжаление ще трябва да бъде върнат.

Много удобен

Банският е много удобен, а принтът е много свеж на фона на предимно черните бански и е плюс. Препоръчвам :)

Additional Product Information


Main fabric

  • 18% Spandex

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.
