The suit measurements below are for reference only. Please allow ±0.25" difference for actual suit measurement.
See below for further details:
Chest - Measure chest just under arms and across shoulder blades, holding tape level (don’t hold your breath). Be sure to cross over the shoulder blades and the fullest part of your chest. Blazer sizes are equal to your chest size. For example, if you have a 38" chest, you would wear a size 38 blazer.
If you are measuring in centimetres divide by 2.54 to obtain the measurement in inches.
Neck - Measure around the middle of the neck, around your Adams apple or fullest part of our neck, keeping tape level. Allow for index finger to fit between the tape and your neck for a comfortable fit.
Sleeve/Arm – With your arm around your hip, bend your arm to a 90 degree angle. Measure from the middle of the back of your neck, across your shoulder and down outside of your arm past elbow to your wrist.
Waist - Look inside one of your pants' waistband. Generally, the size will be written. If you cannot find it, follow these guidelines to find your correct size.
Keep one finger between tape and your body and measure around your natural waistline (usually at the bellybutton). Pants sizes are equal to your waist size. For example, if you have a 38" waist, you should wear a size 38 pants. Remember of your slacks are 1-2" too big or too small, a tailor can easily take them in or out.
Otherwise, use a pair of pants that fit you well, measure from the top of the inner pant leg seam to the opening at the bottom of the pant leg. The number of inches is the inseam length, rounded to the nearest half inch.
The European size of slacks is 16 more than the US size. For example, a size 52 (European) is equivalent to a size 36 (US).
Inseam: With appropriate shoes on, measure from your crotch to your desired pant length. Inseam measurements vary by style. Generally use a pair of pants that fit you well, measure from the top of the inner pant leg seam to the opening at the bottom of the pant leg. The number of inches is the inseam length, rounded to the nearest half inch.
