How to measure for a proper fit:
Chest/Bust: Measure under your arms and around the fullest part of your chest/bust, keeping the tape straight across your back.
Waist: Measure around your natural waistline (smallest part), allowing the tape to sit snug but comfortably.
Inseam: Measure from crotch to bottom of ankle bone
Sleeve Length: Bend your elbow 90 degrees and measure from the center back neck, over the shoulder point to the elbow and down to the wrist.
Hat Size: Use a tape measure or piece of cord. Place the tape measure or cord around your head 1/8 inch above your ear, across mid-forehead, and around your head. Measure your head exactly where the hat will sit. If your measurement falls between sizes, choose the next largest size
Hips: Stand with your heels together and measure around the fullest part of your hips.
Gloves: Measure around the knuckles with the hand flat, thumb extended for common size, those at lower end of a size who want a closer fit order one size smaller, those at upper end of a size who want a looser fit order one size larger.
