◇   Sizing

Find
Your Fit.

All measurements are your body measurements — not the garment. Leather has minimal stretch, so if you're between sizes, size up. Bespoke orders use your exact custom measurements.

{[ { group: 'Upper Body', items: [ ['Chest', 'Wrap the tape around the fullest part of your chest — straight across the nipple line, directly under your armpits, and over your shoulder blades at the back. Keep it snug but never tight: you should be able to slip two fingers between the tape and your body. Hold it perfectly parallel to the floor the whole way around, stand relaxed with arms down, and breathe normally — do not puff your chest out or suck in. Read the number where the end of the tape meets the body of the tape.'], ['Shoulders', 'Best done with a helper. Stand naturally, arms relaxed at your sides, looking straight ahead. Start at the bony tip of your LEFT shoulder — the outer point where the sleeve seam of a well-fitting shirt naturally sits. Run the tape straight across your upper back to the bony tip of your RIGHT shoulder. Let the tape follow the gentle curve of your back rather than pulling it tight in a straight line. That edge-to-edge distance is your shoulder width.'], ['Sleeve', 'Bend your arm slightly and rest your hand on your hip so the arm has a natural angle. Begin at the CENTER BACK of your neck (the small bump at the base of your neck). Run the tape across the top of your shoulder to the shoulder point, then down the outside of your arm, over the elbow, and finish at the wrist bone — right where your hand begins. That single continuous measurement is your full sleeve length.'], ]}, { group: 'Lower Body', items: [ ['Waist', 'Find your natural waist first — the narrowest part of your torso, roughly one inch ABOVE your belly button (not where low-rise jeans sit). Wrap the tape all the way around at that point, keeping it level front-to-back and snug without pressing into the skin. Stand relaxed and do not suck in. Read where the tape meets. This is your body waist — we build the garment around it.'], ['Hips & Seat', 'Stand with your feet together. Wrap the tape around the FULLEST part of your hips and seat — usually 7 to 9 inches below your natural waist, across the widest point of your backside. Keep the tape parallel to the floor the entire way around (check the back in a mirror — it tends to dip). Snug, not tight.'], ['Inseam', 'Stand up straight against a wall, feet about shoulder-width apart. Measure from the very TOP of your inner thigh — the crotch seam — straight down the inside of your leg, finishing at your ankle bone (or wherever you want the hem to fall). Easiest method: take a pair of trousers that already fit you well, lay them flat, and measure along the inside leg seam from crotch to hem.'], ]}, ].map(({ group, items }) => (
