Waist:

Measure around your natural waistline, keeping the tape a bit loose.

Hip:

Stand with feet together and measure around the fullest part of the hip.

Arm Length:

Have a friend measure from your center back to your wrist.

Inseam:

Using pants that fit well, measure the crotch seam to the bottom of the leg.
