Waist: To work out your size, measure your waist in the position your trousers usually sit. As a guide, this is roughly 2 inches (approx 5-6cm) below your belly button. Once you have this measure, minus 2 inches (approx 5-6cm) from it to get your trouser size.

Inside Leg: Measure from the top of your inside leg down to your ankle. You should do this whilst standing to get a more accurate measure.

Please note: The measurements given are body measures and we recommend you do not measure over the clothing. Also please hold the tape measure firmly and not loosely as the measurement needs to be fitted.
