The short answer
- Raw denim hasn't been washed after weaving. It's darker, stiffer and fades to your own wear pattern.
- Raw is not the same as unsanforized. Sanforized raw denim has been pre-shrunk and moves only a little; unsanforized can shrink a lot.
- Expect a stiff first few weeks and some indigo rub-off onto light surfaces.
- Most shrinkage happens in the first wash or soak, and mostly in the length.
Raw denim has a reputation for being difficult. It isn't, but it does behave differently from the soft, washed jeans most people grew up with. Two things decide how a raw pair will treat you: whether the cloth was pre-shrunk at the mill, and how you wash it the first time. Get those right and raw is the most satisfying denim you can own.
Raw vs washed: what's actually different
Most jeans are washed after they're sewn: rinsed, stone-washed or enzyme-washed to soften them and set the color. Raw (also called dry) denim skips that step. The indigo is still sitting fully on the surface, the starch from weaving is still in the cloth, and nothing has been relaxed. That gives you three things washed jeans can't: a deep, even color, a crisp hand, and fades that appear where you bend and rub rather than where a factory put them. Our guide to how denim gets its color explains why indigo fades this way.
Sanforized vs shrink-to-fit
Sanforization is a mechanical pre-shrinking process: the cloth is dampened and compressed so it shrinks before it's cut rather than after you buy it. It was patented by Sanford Lockwood Cluett around 1930 (Wikipedia) and is now standard for most denim. Unsanforized denim, sold as "shrink-to-fit", skips it, so the pair is cut larger and shrinks to size when you soak it.
| Raw, sanforized | Raw, unsanforized | Washed | |
|---|---|---|---|
| Typical first-wash shrinkage | Small, a few percent at most | Up to around 10% | Minimal; already washed |
| Where it shrinks | Mostly length | Mostly length, some waist | Very little |
| How to size it | Close to your real size | Bigger, to shrink down | Your real size |
| Color | Deep, even, unfaded | Deep, even, unfaded | Already lighter |
| Feel at first | Stiff | Stiff | Soft |
Ranges vary with the cloth, water temperature and how long you soak. Heddels puts first-wash shrinkage of unsanforized denim at roughly 5–10% (Heddels on sanforization).
What break-in feels like, week by week
- Days 1–7: stiff at the waistband, knees and behind the knee. Sitting feels firm. This is normal.
- Weeks 2–4: the cloth softens where you bend. Creases start to set at the hips (whiskers) and behind the knees.
- After a month or two: the jeans feel like yours. The waist and seat have relaxed a little; the creases have become the start of fades.
Raw indigo also rubs off, especially when new and damp. This is called crocking. Expect a blue tint on light sneakers, pale sofas and white bags for the first weeks.
Your first wash: a checklist
- Wear them for a while first if you want sharper fades; wash sooner if comfort matters more. Neither is wrong.
- Turn the jeans inside out and button or zip them.
- Soak or wash in cold water, alone or with dark items only.
- Use a small amount of mild detergent, or none for a first rinse.
- Hang to dry. Skip the dryer: heat drives extra shrinkage.
- Measure the inseam and waist (laid flat) once dry, so you know how your pair behaved.
When raw denim is not for you
- You need the jeans to feel soft on day one.
- You have pale furniture, car seats or shoes you can't risk tinting.
- You want the color to stay exactly as bought.
- It's high summer where you live. Raw is usually midweight or heavier; see the denim weight guide.
Raw denim at Jeanszilla
Our raw option is Japanese-style Selvedge, 14 oz raw (+$40), and it pairs naturally with straighter cuts like men's straight and women's straight. We don't quote a shrinkage figure for it here, so if you plan to soak your pair, ask us before you order and use the notes for your tailor to say how you'll wash them. If you're new to the edge itself, read what selvedge denim is.
Questions
Do raw jeans always shrink?
Almost all cotton denim shrinks a little the first time it's washed. Sanforized raw denim shrinks only slightly; unsanforized shrink-to-fit denim can shrink by up to around 10%, mostly in length.
How long should I wait before washing raw denim?
There's no rule. Waiting longer gives sharper, higher-contrast fades; washing sooner keeps them cleaner and softer. Wash whenever they're dirty or smell, and spot-clean in between.
Will raw denim stain my shoes?
It can. Raw indigo rubs off, especially when the jeans are new or damp. It eases after the first few washes.
Is raw denim the same as selvedge?
No. Raw describes whether the denim has been washed; selvedge describes how the fabric edge was woven. Many raw jeans are selvedge, but you can have either without the other.
Can I put raw jeans in the dryer?
Heat drives extra shrinkage, so hang them to dry unless you're deliberately trying to shrink them.
