How to measure

Chest / Bust: wrap the tape around the fullest part, keeping it level under your arms and across your shoulder blades.

Waist: measure around your natural waistline with the tape snug but not tight.

Hip: measure around the fullest part of your seat with your feet together.

Sleeve: measure from the center back of your neck, over the shoulder, down to the wrist.

Inseam: measure from the top of your inner thigh down to where you want the trouser to end, ideally on a pair that fits you well.
