I bought a 4-5 for my 4 and a 1/2 year old daughter. It fits her perfectly. There is no riding up, no slippy straps, and the colors are vibrant. Perfect for swimming lessons and the beach.

Perfect bathing suit! My daughter and I both love. I bought one, and loved so much that I bought another. Seems perfectly sized and super comfortable!!

Cute suit with great colors. Just wash under water after wearing so colors won't fade.

Love this suit! It fits great and maintains its's shape. It washes without fading!!

Great swim suit for kids

We have always bought the cotton Boden swim suits, but this year they stopped making them The cotton ones were great because the sand did not get trapped in the material. The sand gets stuck in this suit and we are disappointed in the quality.

Good suit w/ cross straps that won't fall off during swim lessons. My daughter wears a 7 in most Boden (occasional size 8) but I had to size up to 9/10 on the suits...they are a little loose but the 7/8 were too tight.

We bought one last year and two this year. These are terrific suits. For my slender girls, these ran true to size. The 9/10 fits perfectly on the 56" 60lb 10-year old, and the 7/8 fits perfectly on the 49" 50 lbs 8-year old. Not much growing room but we have a short summer.

We'll see how this holds up once it gets into the water but so far my daughter—who has extreme tactile issues and so is very picky about feel and fit—loves it. It's a tad loose and I ordered a size down, since she is slim and petite. But I knew this going in, which is good since as always, my complaint is how long it takes an order to get to the US from the UK, and that expensive shipping is compounded if a return must be made.

Mini Boden does it again! Adorable swim suit that my daughter absolutely loves. The colors stay vidid no matter how much swimming or washing this suit sees.
