💡 How to Take Accurate Measurements
Chest Circumference
Measure around the fullest part of your chest, usually at the nipple line. Keep the tape measure parallel to the ground and not too tight. Stand naturally with shoulders relaxed.
Shoulder Width
Have someone measure from the peak of one shoulder to the peak of the other, across your back. This is usually the widest point. Keep arms relaxed.
Sleeve Length
Bend your arm at 90° and have someone measure from center back neck, across shoulder, down to wrist. Alternatively, measure from shoulder seam to wrist.
Waist Circumference
Measure where you normally wear pants at natural waist (usually above hips). Don’t pull tape too tight. Measure standing straight, not sitting.
Inseam (Pants Length)
Measure from inner thigh straight down to ankle. Stand with feet shoulder-width apart. This is crucial for pants length. Pants should break slightly at shoe top.
Pro Tips for Perfect Fit
Common Sizing Issues
Too Tight in Chest
Go up one jacket size. If slightly tight, tailor can let out (usually 1-2 inches max).
Sleeves Too Long
Request “S” (Short) or “XS” (Extra Short). If only ½-1 inch too long, tailor can shorten inexpensively.
Sleeves Too Short
Request “L” (Long) or “XL” (Extra Long). Lengthening is expensive or sometimes impossible.
Jacket Too Long
Should hit at knuckles. If too long, tailor can shorten by up to 2 inches.
Pants Too Long
Easily hemmed by tailor. Budget $15-30. Ensure proper break length at shoe.
