For the most accurate results, measure yourself in your undergarments. Give all measurements in inches. If your measurements are between sizes, order the larger size. For greatest accuracy, have someone take your measurements rather than yourself. The tape measure should be pulled snug, not tight. Check the size scale of all garments being ordered to ensure that all measurements were taken at the proper points. Pants, Jeans & Bib Overalls Waist: Measurement is taken at the top of the hipbone over shirt (not over pants). Tape should only be held snug, do not hold tape tight. Inseam: Measure from the base of the crotch to the top of the shoe or boot. For jeans, add one inch. In some styles, Dickies offers an Unhemmed Inseam (UU) of 37" or (UL) is 39". Chest: Measure around the fullest part of your chest, keeping tape firmly under your armpits and around your shoulder blades. Hold tape level and firmly but not tight. NOTE: It is advisable to ask the person being measured how he or she wears their pants. Not everyone wears their pants or jeans the same length or height on their hips. Shirts & Coveralls Neck: Measurement is measured around the base of your neck, inserting your forefinger between the tape and your neck to allow ease in fit. Sleeve Length: Bend your arm slightly. Measure by placing one end of the tape at the bottom of the collar at the center back and mark the distance around the elbow to the bottom of the wrist.
