Sizing Guide

Uniform Measurement Guide for Parents

To help ensure your child’s uniform fits comfortably and looks great, we recommend taking a few quick measurements at home before placing your order. You won’t need any special equipment—just a soft tape measure and this simple guide.

📏 What You’ll Need:

A flexible measuring tape (or a piece of string + a ruler)
A notepad to record your child’s measurements
Your child standing in light, fitted clothing for accuracy

🧥 Tops – Polo Shirts, Peter Pan Blouses and Jumpers

Measurement needed: Chest

Measure around the fullest part of your child’s chest, just under the arms.
Keep the tape measure snug but not tight.
Make sure your child is standing straight with arms relaxed at their sides.
Reference the size chart for jumpers and polos based on chest measurement to determine the right size: Jumper Size Chart and Polo Size Chart

Tip: If your child is between sizes, we recommend sizing up for comfort and growing room.

👖 Pants and Shorts

Measurement needed: Waist and Inseam

Measure around the natural waistline—this is typically just above the belly button.
Make sure the tape is level all the way around and not too tight.
Measure the inseam from the top of the inner leg down to the ankle while standing straight.

👗 Skirts, Pinafores, and Skorts

Measurements needed: Waist and Length

Waist: As above.
Length: Measure from the natural waistline down to the desired length (e.g. just above the knee or mid-calf, depending on school guidelines).
Skorts should sit comfortably at the waist and fall to an appropriate school-approved length. They’re designed with built-in shorts for flexibility and modesty.

🧦 Additional Tips

Double-check school guidelines for uniform fit or length preferences.
Refer to the sizing chart on your school’s All Basics store page for exact garment measurements.
If in doubt, go one size up—children grow quickly, and most items are designed with room for growth.
Keep your notes for future re-orders!
