Where a leather jacket should sit at the shoulder, sleeve and hem — and why it should fit slightly snug on day one.
How should a leather jacket fit?
A leather jacket should fit close, not tight. The shoulder seam sits right at the edge of your shoulder. The sleeve ends at your wrist bone. You can fit a flat layer underneath — a shirt or a light knit — and still close it comfortably. If it feels a touch snug when it's new, that's correct. Leather gives a little as you wear it; a jacket bought roomy only gets roomier.
Everything below is how to check each of those points yourself.
The shoulder is the one thing you can't fix
Start here, because it's the part a tailor can't easily change. The shoulder seam should land exactly where your shoulder ends — not drooping down your arm, not pulling up onto the joint. If the shoulders are wrong, the jacket is the wrong size. Sleeves can be shortened. Shoulders can't, not without rebuilding the jacket.
Sleeves
Sleeves should reach your wrist bone — roughly where a watch sits. With arms down, you want to see a little shirt cuff, not three inches of it. With arms forward, the cuff shouldn't ride halfway up your forearm. Leather sleeves relax slightly with wear, so err on the side of just long rather than already short.
Body and closure
Closed, the jacket should sit close to the torso without straining at the zip or buttons. Look for horizontal pulling lines across the chest or back — that's the leather telling you it's a size too small. A clean, smooth front when closed is the target. A little ease, not a lot.
Length
- Café racer / minimalist: sits at or just above the waistband. Short and clean by design.
- Biker / moto: hits at the hip, sometimes a touch shorter.
- Bomber: ends at the waist with a banded hem that gathers slightly.
The general rule: a leather jacket should end somewhere between your waistband and the top of your hip. Long enough to look intentional, short enough to keep the line sharp.
Room for a layer
Most people wear a leather jacket over a shirt or light knit, so try it on over what you'll actually wear it with. You want room for one flat layer — not a hoodie, not a heavy sweater. If you size up to fit thick layers underneath, the jacket will swim on you the rest of the year. Layer thin under leather, not thick.
Men's and women's notes
The principles are the same; the cut isn't.
Men's jackets run straighter through the body. Watch the shoulder and the chest — broader builds often need to size for the shoulders and have the body taken in slightly, rather than sizing up everywhere.
Women's jackets are shaped through the waist, so the fit through the bust and the nip at the waist matter as much as the shoulder. A women's biker is meant to sit close; a women's bomber or oversized cut is meant to have ease — read the style, not just the size.
A note for taller builds
If you're tall, the usual problem isn't width — it's sleeve and body length. A jacket can fit perfectly at the shoulder and still come up short at the wrist and hem. Check those two points specifically. We flag the sizing on each product page so you can choose with this in mind, and you can always check the size and fit notes before you buy.
How leather changes as you wear it
New leather is at its firmest on day one. As you wear it, the leather warms to your body, softens, and gives a little where it flexes — elbows, shoulders, the closure. Vegetable-tanned full-grain lambskin does this beautifully; it relaxes into your shape rather than just stretching out. (More on why in Vegetable-Tanned Leather: Why It Matters.)
This is exactly why a leather jacket should fit slightly snug when it's new. It's not going to shrink. It's going to mould to you. Buy the one that fits today and it becomes the one that fits like it was made for you.
Getting fit right, without the guesswork
Fit over the internet is the one real risk with leather, so we built around it. Every STREGA jacket comes with a 30-day guarantee — wear it, layer it, live in it, and if the fit isn't right, return it. We'd rather you take the size you're unsure about, try it properly at home, and send back the one that doesn't work than settle for a jacket that almost fits. A jacket you keep for a decade is worth getting right in the first week.
FAQ
Should a leather jacket be tight or loose?
Close, not tight. It should fit snug when new — leather relaxes and moulds to you with wear, so a jacket bought roomy only gets roomier. You want room for one flat layer underneath.
Where should the shoulder seam of a leather jacket sit?
Right at the edge of your shoulder, where the shoulder ends and the arm begins. The shoulder is the hardest part to alter, so get it right first — sleeves can be shortened, shoulders can't.
How long should a leather jacket be?
Generally between your waistband and the top of your hip. Café racers sit shortest, bikers at the hip, bombers at the waist with a banded hem. Long enough to look intentional, short enough to keep the line clean.
What if the fit isn't right when it arrives?
Every STREGA jacket comes with a 30-day guarantee. Try it properly at home, and if the fit isn't right, return it — we'd rather you get the size right than settle.
