Good purchase
Got this for my kid’s swim lessons when I have to get inside the pool. It is a very pretty red. Baywatch tone. It keeps everything in place but I believe I should’ve sized up. It feels like it shrinks some after washing. I followed the size guide and while I’m a 8-10US I should’ve had sized up even with their suggestion. Amazon suggest the wrong size always. Great fabric. Great coverage. With the money.

KIDS!
I have ordered 20 size and it's so small that even my 5 years old toddler girl can't fit it

Lined swimsuit
I really liked that this suit was lined, I did however return it as it seemed long in the torso when I compared to my kiddos other suits. The fit was loose across the chest and straps. It was the same size I buy in other brands but my first time trying Arena. I think I would order again, as it seemed like a quality suit, but would size down to see if that helps.

The best
The price was the main reason but definitely Arena it’s the best swimsuit for me. The only thing is the measure it was to small for me.

Me gustó mucho el traje de baño, lo encontré un poco ajustado pero no es tanto y con el tiempo se va estirando. Normalmente soy talla G y pedí un 36.

This bathing suit seems to be good quality. It fits as expected . The test will be how it holds up to chlorine
