Yes, mostly. Learning how to unshrink a linen shirt is worth ten minutes of your time, because linen responds to the treatment better than almost any other fibre.
You will not always get every centimetre back. A first-wash shrink is usually recoverable in full. A shirt that has been through a hot wash and a hot tumble dry several times is a harder case, and this covers both.
What happened when it shrank
Linen is a bast fibre, spun from the stem of the flax plant. During spinning and weaving the yarn is held under tension, and it comes off the loom slightly stretched.
Water and heat let that tension go. The fibres swell, the yarn contracts back toward its relaxed length, and the cloth pulls in. Nothing has been destroyed. The fabric has simply gone back to a shape it prefers.
That is why unshrinking works. You are not repairing damage, you are re-applying the tension a loom applied in the first place.
How much linen shrinks
Untreated linen loses somewhere between 3 and 10 per cent on its first hot wash. On a shirt with a 74 cm body length, 5 per cent is nearly 4 cm, which is easily enough to change how it sits.
Most of it happens once. Pre-washed and garment-dyed linen has had that movement taken out at the mill, which is why it barely changes afterwards. Cotton-linen blends shrink less than pure linen, roughly in proportion to how much linen is in them.
The method
Linen is one of the few fibres that is stronger wet than dry, by around 20 per cent. That is what makes this safe to do.
- Fill a basin with lukewarm water, no hotter than hand warm. Heat is what caused this, so keep it gentle.
- Add a tablespoon of hair conditioner or baby shampoo and stir it through. Both relax the fibre and let it slide.
- Submerge the shirt and leave it 20 to 30 minutes, pressing it under occasionally.
- Lift it out and press the water out against the side of the basin. Do not wring it.
- Roll it in a dry towel and press again, until it is damp rather than dripping.
- Lay it flat and stretch it gently, working outward from the centre in the direction you need. Length first, then across the chest.
- Hold the new shape. Pin it to a towel, or weight the hem and cuffs, and let it dry away from direct heat.
Check it as it dries and stretch again while there is still moisture in the cloth. One more pass at the halfway point is usually worth more than a longer soak.
How much you will get back
Honest expectations help here.
- One accidental warm wash. Expect to recover nearly all of it, often on the first attempt.
- Repeated hot washing over months. Expect most but not all. Two or three rounds of soaking and stretching will get you further than one long one.
- Hot tumble drying, repeatedly. The hardest case. Heat sets the relaxed shape, and some of it will not come back.
- Blends with elastane. The elastane degrades with heat rather than contracting, and that damage is permanent.
Work on one dimension at a time. Trying to pull length and width at once tends to distort the shoulders.
Awkward areas
Sleeves are best stretched with the shirt laid flat and the sleeve smoothed straight, pulling from cuff to shoulder rather than sideways.
Collars and plackets have interfacing inside and move much less than the body of the shirt. If the collar is tight, the honest answer is that it will stay tight.
For body length, weight the hem while it dries. Gravity does the work more evenly than your hands will.
Stopping it happening again
Wash cold. That single change prevents most linen shrinkage, and linen is easy to clean because the fibre releases soil readily.
Use a gentle cycle and a half-full drum. Agitation contributes as much as temperature. Skip fabric softener, which coats the fibre and dulls the dry handle linen is bought for.
Line dry, or tumble on low and take the shirt out while it is still slightly damp, then hang it to finish. Linen ironed or hung damp comes out far better, and pulling it into shape at that point undoes the day's shrinkage before it sets.
Our linen pieces are labelled to match. The Yumemi 7/8 Shirt in 100 per cent linen, the Igen Linen Pants and the Yasumi Linen Pants all take a cold machine wash, line drying or a low tumble, and a warm iron. The Shinu Sleeve Shirt, a linen blend, is hand wash cold and line dry only.
If it will not come back
A shirt that has lost length but still fits through the chest can be worn open over a tee, where the hem matters less.
Failing that, a shrunken linen shirt makes a decent short-sleeve conversion, since the sleeve is the easiest part to shorten cleanly. A tailor will charge much the same as a trouser hem, which the cost of hemming pants covers.
Where to go next
For the drying and cleaning question that causes most of this, read can you dry clean linen shirts. Cotton behaves similarly but not identically, which care instructions for cotton covers, and linen versus cotton for summer compares the two. Shop linen pants.
