Girls wearing M&S school uniform

For good measure

1. Chest
Measure the chest at the fullest part, placing the tape close up under the arms

2. Waist
Measure the natural waistline

3.Collar
Measure around the base of the neck where the collar sits

4. Inside leg
Measure from the crotch to where the trouser hem falls on the shoe

5. Height
Without shoes, place feet together flat on the floor, and measure from the top of the head to the ground

HANDY TIP
If you’re buying a school blazer, it’s also a good idea to measure from the centre of the neck to the hemline
