Decormi Jacket
Size Guide
Every Decormi jacket is cut to body measurements, not garment measurements. Measure yourself with a soft tape, match the numbers below, and use the measuring notes further down if you are unsure where the tape should sit.

How to measure
Shoulders
Measure straight across your upper back, from the outer edge of one shoulder to the other. Stand tall with your shoulders relaxed — hunching adds up to an inch.
Chest / Bust
Wrap the tape around the fullest part of your chest, under the arms and level all the way round. Keep it snug, not tight, and breathe normally with your arms at your sides.
Sleeve
Start at the tip of your shoulder and run the tape down the outside of your arm to the wrist bone. Keep the elbow slightly bent so the sleeve does not ride up when you move.
Waist
Measure around the narrowest part of your waist, roughly halfway between your lowest rib and your hip bone. Let the tape rest on the body without pulling it in.
Still between two sizes?
Leather softens and moulds to you with wear, so a jacket that feels close-fitting in the first week settles in. Pick the smaller size for a sharp, fitted look; go one size up if you plan to wear a hoodie or a jumper underneath. Send us your chest, shoulder and sleeve measurements and we will confirm the size before your order ships.
