How To Measure

Measuring Your Body

Use a soft measuring tape for accurate measurements. Measure over light clothing or directly on skin.

1. Chest / Bust

Measure around the fullest part of your chest or bust, keeping the tape parallel to the floor. Do not pull too tight.

2. Waist

Measure around the narrowest part of your natural waist, typically about an inch above your belly button.

3. Shoulder

Measure from the edge of one shoulder across to the other, straight across the upper back.

4. Sleeve

Measure from the top of your shoulder seam down to your wrist. Keep your arm slightly bent at the elbow.

Fit Tips

Getting The Right Fit

Measure your chest, not your usual clothing size — jacket sizing varies by brand and style. Always go by measurements.

If you plan to layer — over a hoodie or thick jumper — size up one size for a comfortable fit over layers.

Leather stretches slightly — over time, real leather will mould to your body and ease slightly. A snug fit now will become a perfect fit over time.

Still unsure? — Contact us at nsmjackets@gmail.com with your measurements and we will advise the perfect size before you order.

How to Find Your Size

Our jackets run true to standard US and UK sizing across men's and women's ranges. Measure yourself against the chart on this page, or compare to a jacket you already own for the closest match.

To measure chest size, wrap a tape measure under your arms at the fullest part of your chest, keeping it level and snug but not tight. For sleeve length, measure from the center back of your neck, across your shoulder, and down to your wrist. If you're between sizes, we generally recommend sizing up for a more relaxed fit, especially for biker and bomber styles meant to be worn with a layer underneath.

Still unsure? Reach out through Contact Us before ordering, and our Return & Exchange policy has you covered if the fit isn't right.
