Hat size – Measure across your brow just above your ears, keeping the tape parallel to the floor (for females). For male and generic sizes, divide the measurement in inches by 3.14 to obtain your hat size to the nearest 1/8".
Collar – Measure around your neck at the point where the collar is worn, pulling the tape tight enough to remove gaps between the tape and the skin, but not so tight as to depress and discolor the skin. Round up to the next ½" for your collar size.
Chest/bust – While standing erect, measure around the largest part of the chest or bust with the tape passing under the arms, remaining parallel to the floor, and snug*.
Waist – Measure around your waist where the trousers are worn; generally this is the smallest part of the waist. Pull the tape snug*.
Hips – While standing with your feet together, measure around the fullest part of your hips or seat, keeping the tape parallel to the floor and snug*. Remove wallets and cell phones from your pockets prior to taking the measurement.
Skirt length – Measure from your waistline to the center of your kneecap.
Inseam – Measure the inside seam from the crotch to the bottom of the trouser leg.
*Snug means that the tape is tight, but yet loose enough to slide your hand under the tape.
