Whatever it is, don’t worry—it’s actually possible to (intentionally) shrink baggy clothes in the wash so they fit perfectly. The key is to check the type of fabric first since the shrinking process varies depending on what your clothes are made out of. Keep reading to learn how to shrink cotton, denim, polyester, wool, and other types of fabric in your washing machine.

Use the hot water setting on your washing machine. Heat is the best way to shrink nearly any kind of fabric. When clothing is made, the fabric is stressed and pulled taut, making it longer and wider. Heat relaxes the fabric, causing the threads to unstretch and shorten, resulting in smaller, shrunken clothes.^{[1]XResearch source}
- Clothes made with natural fibers (like cotton and denim) will shrink more easily than clothes made with synthetic fibers like polyester. You can definitely shrink synthetic clothing in the wash, but it might not shrink as much.^{[2]XResearch source}
- This shrinking method works for most types of fabric, but don’t try it with delicate fabrics, like wool, silk, and cashmere. Hot water and high heat can damage delicate fabrics.
- Clothes that are labeled “pre-washed” or “pre-shrunk” may not shrink in the wash. They’ve likely already been shrunk to their smallest size by the manufacturer.
2
Dry the clothing on a high heat setting. Just like hot water causes fabric to shrink, so does hot air in the dryer. Use the highest heat setting to shrink your clothes in the dryer.^{[3]XResearch source}
- Don’t have access to a dryer? Use a blow dryer on a high heat setting to dry your clothes and get a similar effect.^{[4]XResearch source}

If the piece you’re trying to shrink is really oversized or made with synthetic fibers, it might not shrink down to the size you want on the first attempt. Try re-washing and drying it with hot water and high heat to shrink it some more.^{[5]XResearch source}

Wool & Cashmere

1
Machine wash the clothing with warm water. Wool fibers are made up of animal hairs that consist of hundreds of tiny scales. When these fibers are exposed to heat and agitation in a washing machine, the scales interlock and mat together, shrinking the fabric.^{[6]XResearch source}
- Machine washing wool or cashmere in warm water can damage it. If you’re really attached to this piece of clothing, a safer alternative is to hand wash it in a bucket with warm water.^{[7]XResearch source}
2
Dry the clothing on a medium heat cycle. Wool and cashmere shrink quickly, so avoid using the high heat setting on your dryer. Medium heat is perfect. Otherwise you could end up with a doll-sized shirt or wool pants that don’t button anymore.^{[8]XResearch source}
- If you need to shrink your clothes without a dryer or are worried about shrinking your wool/cashmere clothing too much, use a blow dryer instead! Dry the clothing with the blow dryer until it’s the size you’re aiming for.^{[9]XResearch source}
3
Check on the clothing every few minutes. This will help you catch the clothing if it’s starting to shrink too much. Once the item looks to be the right size, take it out of the dryer.^{[10]XResearch source}
- If you pull your wool or cashmere clothing out of the dryer and it’s too small, don’t panic. Mix 2 tablespoons (30 mL) of fabric conditioner with warm water in a container and soak the clothing in it for 15 minutes. Then, press out the excess water with a towel, stretch it to the size and shape you want, and let it dry on a flat surface.

Silk

Machine wash the silk with warm water. Like with most fabrics, heat will cause silk to shrink. How much it shrinks depends on the type of silk you’re working with. Loosely woven silks will shrink more than tightly woven silks, so the amount of shrinkage you get may vary.^{[11]XResearch source}
- Machine washing silk with warm water can damage it, so proceed with caution. For a safer approach, soak your silk clothing in warm (not hot) water for a few hours, stirring it regularly.
Low heat will shrink your silk, and there’s less chance of damage than if you were to use the high heat setting on your dryer.^{[12]XResearch source} However, tumble drying silk always comes with the risk of damage. If your silk has already shrunk enough from washing it in warm water, consider hanging it up to air dry instead of tumble drying it.^{[13]XResearch source}
You don’t want your silk to shrink more than you anticipated, so pull it out of the dryer every few minutes to see how it’s looking. Once it’s reached your desired size, stop drying it so it doesn’t shrink more.

Question
How do you shrink nylon pants?
Community Answer
Nylon clothing typically does not shrink, but will stretch out over time if it has any spandex rubber woven in. Nylon itself may melt in hot dryer. Best bet is to have the pants altered by a seamstress.
