Please note; WE RECOMMEND TO TRY THE WATERPROOFS ON YOUR CHILD, BEFORE ASSUMING THEY ARE TOO BIG; OUR WATERPROOFS ARE MADE WITH PLENTY OF ROOM TO PLAY, BEND AND CLIMB - THEY LOOK MUCH LARGER WHEN LAID FLAT/HELD UP AGAINST YOUR CHILD. HOW TO MEASURE
Our sizing is based on a child’s height; for example, 100cm is designed to fit children approximately 100cm tall, measured from top of head to toe.
EXAMPLE : IF YOUR CHILD IS 92CM THE SIZE 90CM (2-3 years) WILL FIT YOUR CHILD AND ALLOW ROOM FOR GROWTH, please do not size up.
It is suitable to size up if your childs height is close to the measurement (IF YOUR CHILD IS 98CM THEN SIZE 100CM WILL FIT)
We hand measure all of our waterproofs by laying them down on a flat surface. To get the best possible size, we recommend finding an item of clothing that fits your child perfectly and laying down on a flat surface. Compare our measurements with yours so that you can find the perfect size for your child.
To find the best measurement for a jacket, we recommend looking at the Cuff to Cuff measurement. Ask your child to stand like a scarecrow with their arms out straight, and measure from one cuff to the other.
Wet Wednesdays sizing is specially designed in the UK to allow room for growth and the freedom to move & play.

These jackets are just the BEST! The fleece lined jacket helps keep my little one warm and dry. The zip is easy to do up and the Velcro fastenings on the wrists help keep gloves in place and the cold out. We love the designs and now have both the pink unicorn mermaid AND the purple fairy forest fairy. My little girl loves spotting all the different drawings on them. One of the best things too is how easy they are to clean. My little one loves the mud but most times we just give it a wipe over and it’s ready to go again! So no need to wash it everytime- winner 🙌🏻
