Your journey to the right size
Here's exactly what happens when you click "Calculate your size"
Step 1
Click "Calculate your size"
On any uniform product page, you'll see a "Calculate your size" button near the size options. Click it to open the recommender — it pops up right on the page.
Available on every product — shirts, trousers, blazers, skirts & more.

Step 2
Enter your child's basic details
A quick form asks for gender, age, weight, and height. Use approximate values — you don't need exact numbers. Recent school medical records work perfectly.
No measuring tape needed — a bathroom scale and wall mark is enough.

Step 3
Set up the body profile
For an even more precise recommendation, you can add chest, waist, and hip measurements. A built-in visual guide shows you exactly where and how to measure your child.
Don't have a tape? Skip this — the basic details still give a strong result.
Step 4
See your perfect size
The recommender shows your child's ideal size for that specific product — with a visual overlay of your child's body profile on the garment. You can see exactly how the fit works and compare between sizes, so there are no surprises.
Every recommendation is unique to each garment's real dimensions.
