Reblocking a Shrunken Maison Kitsuné Wool Cardigan in Singapore
This size S Maison Kitsuné wool cardigan shrank in a home wash and was relaxed and reblocked back to its original size. It had come out of the wash shorter in the body and sleeves and narrower across the chest. Its care label allowed a hand wash at ambient temperature, and it had not been put in a dryer.
Wool can shrink without a machine or a dryer, because the movement of the fibres in water is what draws a knit in. This page records what happened to this cardigan, measured on the same table before and after, not an outcome to expect from every shrunken knit.
What condition was the Maison Kitsuné cardigan in when it arrived?
The cardigan had shrunk all over. It is a Maison Kitsuné Baby Fox merino cardigan in light beige, size S, with a crew neck, a button front, ribbed edges and the brand's embroidered fox on the chest. After a wash at home it was shorter from collar to hem, narrower across the chest and shorter in the sleeves.
We measured it on arrival along the button placket, across the chest below the armholes and along each sleeve from shoulder to cuff, and measured it again the same way when the work was finished. The photographs on this page are those measurements.
Why does a wool cardigan shrink when it is hand washed?
Wool shrinks in two ways. A knit is made under tension, and when the fibres are wetted they relax and the knit draws in. Separately, each wool fibre is covered in small overlapping scales; with water, warmth and movement, the scales catch on one another and the fibres lock together. That second process is felting, and it is what makes a knit dense and matted.
Neither needs a washing machine. Rubbing, wringing, a long soak, or rinse water at a different temperature from the wash water all give the fibres the movement they need. A hand-wash label means the knit will tolerate water handled gently, not that any hand wash is safe for it.
How did Rosabelle reblock the cardigan?
Measuring before anything else
The cardigan was measured along the placket, across the chest and along the sleeve before any work started, so the result could be checked against the same points afterwards rather than judged by eye.
Relaxing the fibres
The knit was relaxed so that it could move again. Pulling a shrunken knit without doing this first strains the yarn and stretches it unevenly.
Reblocking body, sleeves and edges together
The body, sleeves and ribbing were eased back toward size together, and the cardigan was dried in that shape so it held it. The ribbed cuffs, neckline and hem were kept to their own proportion, because a rib that is stretched with the body stops gripping.
What did Rosabelle deliberately avoid, and why?
- Stretching it by hand while wet. The areas you grip move more than the rest, and the knit comes back uneven.
- Heat to speed the drying. Warmth with movement is what felts wool; drying had to be controlled and in shape.
- Working the length on its own. Easing only the body leaves the sleeves short and the proportions wrong.
- Pulling the ribbing out with the body. Overstretched ribbing loses the grip that holds the cuffs and hem in place.
What was the result?
The cardigan went back to its original size S dimensions: body length, chest width and sleeve length all returned, measured at the same points as on arrival.
What does this case show about shrunken wool?
A hand-wash label does not make a knit safe from shrinking; how the wash is handled matters as much as the temperature. It also shows that a knit which has drawn in, rather than matted, has room to come back. The distinction between the two is what an assessment is for, and it is why the result on this cardigan is evidence about this piece, not a forecast for every shrunken sweater.
How should you care for a merino wool cardigan?
Do:
- Follow the care label. Woolmark's care guidance starts from it too.
- Keep wash and rinse water at the same temperature, and handle the knit gently.
- Press water out in a towel, then dry the cardigan flat in its own shape, out of direct sun.
- Bring a shrunken knit in as it is, and tell us how it was washed.
Don't:
- Wring, rub or soak wool for long.
- Tumble dry a wool knit unless the label allows it.
- Hang a wet knit; its own weight pulls it out of shape.
- Try to stretch a shrunken knit back by hand before it has been seen.
The honest note
Can every shrunken wool sweater be reblocked to size?
Not always. We do our best, but many factors will affect the outcome. Complete recovery is possible on some garments but cannot be guaranteed. How far a knit has felted, how it was knitted, what it is blended with, and what has already been tried on it all change the work. This cardigan came back fully; a knit whose fibres have locked into a dense, matted surface does not move the same way, and each one is measured and assessed before any work starts.

Common questions
Questions about shrunken wool knitwear
Can a shrunken wool cardigan be restored to its original size?
Wool shrinks in two ways: the knit draws in as the fibres relax from the tension they were knitted under, and the fibres felt, their surface scales locking together under water, warmth and movement. Relaxing and reblocking works on the first far more than the second. This size S Maison Kitsuné cardigan was reblocked to its original size. How much comes back depends on how far the fibres have locked, so each knit is assessed before any work starts. Complete recovery is possible on some garments but cannot be guaranteed.
Why did my wool sweater shrink when the label said hand wash?
A hand-wash label means the knit tolerates water, not that any hand wash is safe. Rubbing, wringing, a long soak, or a change in water temperature between wash and rinse all give wool fibres the movement they need to tighten. This cardigan was labelled hand wash at ambient temperature, was washed at home and was not put in a dryer, and it still shrank in length, chest and sleeve.
Can I unshrink a wool sweater at home by stretching it?
Pulling a wet knit by hand stretches it unevenly: the ribbing, the seams and the areas you grip move more than the rest, and a knit that has felted does not move at all. On this cardigan the body, sleeves and ribbed edges had to come back together, with the ribbing kept to its own proportion rather than pulled out with the body.
How much does it cost to fix a shrunken wool sweater in Singapore?
Reblocking a shrunken knit is quoted after the piece is assessed, because the work depends on how far it has shrunk and whether the fibres have felted. Routine sweater cleaning at Rosabelle is on the price list, and the reblocking quote is given before any work starts.
How should I wash a merino wool cardigan to stop it shrinking?
Follow the care label first. For a hand-washable knit, keep the wash and rinse water at the same temperature, press the water out rather than wringing, do not soak it for long, and dry it flat in its own shape out of direct sun. Never tumble dry wool unless the label allows it. If the knit is valuable or you are unsure, have it cleaned professionally.
