A shrunken sweater can sometimes be partly brought back into shape, but that depends strongly on the material and the cause of the shrinking. With felted wool or fibres damaged by heat, recovery is often limited or not possible. So do not expect miracles: sometimes you get half a size back, sometimes nothing. Always check the care label first and consider professional help for precious clothing.
Why does clothing shrink?
Clothing shrinks when fibres pull closer together under the influence of heat, moisture and movement. With wool there is something extra: the fibres hook into each other and felt. That is the familiar story of the sweater that was washed at 60 degrees and then fits a child. Cotton shrinks mainly with hot washing and drying in the tumble dryer. Synthetic fibres such as polyester and polyamide shrink less, but can lose their shape at high temperatures.
What is or is not possible therefore depends on the fibre. So read the label first: it states the composition and often also the washing advice.
Step by step: the soaking method
A frequently mentioned method is to gently bring the garment back into shape while wet. Not every material is suitable for this.
- Fill a basin with lukewarm water. Feel with your hand: it should feel comfortable, not warm.
- Use only a suitable product. For wool, choose a product meant for wool and follow the instructions.
- Let the garment soak for ten to fifteen minutes. Do not squeeze and do not wring.
- Press the water out. Roll the sweater in a towel and press gently, without twisting.
- Gently pull it into shape. Lay it on a dry towel and gently pull the length and width back, in small steps.
- Let it dry flat. Out of the sun, away from the radiator and not on a hanger.
Do not force the fabric and stop if seams, stitches or fibres start to distort. Fibres that tear or fray no longer give.
By material: what is realistic?
| Material | Chance of recovery | Note |
|---|---|---|
| Wool, merino | Reasonable with light shrinkage | A felted sweater is harder to get back |
| Wool with cashmere | Reasonable with light shrinkage | Stretch gently, never force |
| Cotton | Variable | Part of the size often comes back |
| Viscose and polyamide | Limited | The shape may remain |
What rarely works
- Steaming or ironing to stretch. Heat can damage the fibres further.
- Wearing it wet to get it into shape. That gives shapeless patches.
- Pulling harder. If the sweater does not give, it stretches unevenly.
- Washing warm again. That increases the shrinkage.
How do you recognise that wool has felted?
Felted wool feels thick, stiff and a little hard, and you can no longer see the knit stitches clearly. That is a sign that the fibres have hooked into each other and cannot go back. If the sweater is only smaller but still soft and supple, there is more chance of recovery. Test it carefully: take a small piece of fabric between your fingers and pull gently. If it gives, you can continue with the soaking method. If it stays stiff, you had better stop.
A shrunken cotton top
Cotton shrinks mainly in the first washes and after hot drying. With cotton, recovery differs greatly. Only try to gently bring it back into shape if the care label allows it.
When is it done?
If the sweater is still too small, you can pass it on to someone it fits, or use it as a warm layer under a coat. Sometimes an almost-shrunken top is a nice short fit, depending on how you wear it. Do you have an expensive piece? Then consult a dry cleaner or a specialist. They can sometimes do more than you can at home.
First the label, then the approach
Before you try anything, look at the label of the garment. With 100% wool, recovery depends mainly on the degree of felting. If the fabric contains a lot of polyester or polyamide, the chance of recovery is smaller, because those fibres hold their shape differently. With a mixture of fibres, the result depends on the largest component. If in doubt, professional advice is safer than experimenting further.
Prevention is better than cure
A few habits reduce the chance of shrinking considerably. Prevent new shrinking by following the wash and dry label precisely. More details are on the care instructions page.
With natural fibres, the treatment is extra important. On the pages about merino wool and cashmere you can read what to expect from those materials. The Trenton in black is made of 100% merino wool, the Augusta in cream of 90.2% wool with 9.8% cashmere. After wearing, let merino wool air first and wash only when needed.
What else can you do differently?
Washing is often not necessary. Hang knitted pieces to air overnight after wearing and remove stains with a damp cloth. For pieces made of viscose, polyamide or lyocell the same applies: follow the specific care label. See the whole collection at knitwear for women.

Frequently asked questions
Can I make a shrunken wool sweater bigger again?
Sometimes partly, but not always. Check the label first and do not force felted or damaged wool.
Does hair conditioner really help?
Rather use a product specifically suitable for wool or cashmere. Hair conditioner is not official care advice for clothing.
How do I prevent my sweater from shrinking again?
Always follow the temperature, programme and drying method on the care label.
