Complete Guide to Effectively Shrinking Your Clothes

Understanding the garment shrinking process

Shrinking a garment involves reducing its size so that it better fits the body. This is possible thanks to the properties of textile fibers, which tend to shrink when exposed to heat and humidity.

During washing or drying, the mesh that makes up the fabric will tighten. The fibers will curl up and the garment will shrink slightly. This phenomenon is more or less pronounced depending on the type of textile.

Natural fabrics made from cotton, wool, silk, or linen are quite elastic and lend themselves well to shrinking. Synthetic materials such as polyester also shrink, but to a lesser extent.

Note: garments containing elastane shrink very little. Their elasticity allows them to retain their original size.

In this article, we will look at how to take advantage of the shrinkage capacity of fabrics to precisely adjust the size of your oversized clothes.

The basic principles of shrinking a garment

To successfully shrink a garment, you need to follow a few basic principles:

• Use heat, with a high-temperature wash cycle, a tumble dryer, or boiling water.
• Choose a program with a slow spin cycle to avoid damaging the fibers.
• Wash the garment inside out to limit wear and tear.
• Choose the right amount of detergent to avoid softening the fibers.
• Avoid stretching the garment while it dries. Letting it dry flat or hanging it up allows the fabric to shrink.
• Proceed in stages, repeating the process for gradual shrinkage without damaging the fabric.
• Follow the care instructions on the garment's label.

By applying these tips, you will maximize your chances of achieving the desired result. Now let's see how to adapt the method to different types of clothing.

Tips for shrinking your clothes according to their type

How to shrink pants that are too big?

To shrink jeans or pants that are too big at the waist or legs, using a dryer is very effective.

Using a dryer to shrink jeans

• Wash the pants inside out at the temperature indicated on the label.
• Hang them up gently to dry.
• Once they are wrung out but still damp, put them in the dryer for 15 minutes at a high temperature.
• Repeat the process until you achieve the desired fit, without exceeding 30 to 40 minutes in total.
• Hang the pants up again to let them cool and dry completely, without stretching them.

These short drying cycles combined with high heat will shrink the jeans gradually and evenly.

How do you shrink a jacket?

To adjust a suit jacket or denim jacket that has become too loose in the shoulders or back:

• Fill the washing machine with 2 or 3 thick towels.
• Add the jacket and run a cycle at 60°C.
• The towels will massage the jacket during the wash and activate the shrinkage of the fabric.
• Repeat the process if necessary.
• Hang the jacket delicately to dry, without stretching it.

How do you shrink a sweater or sweatshirt?

Sweaters and sweatshirts are wardrobe staples that tend to stretch with repeated washing. Fortunately, it's easy to restore them to their original size.

How to shrink a wool sweater that's too big?

To shrink a wool sweater, follow these steps:

• Fill a basin with boiling water.
• Immerse the wool sweater and let it soak for 30 minutes.
• Gently remove the sweater and stretch it slightly to restore its original shape.
• Lay it flat on a towel to dry, without stretching it.

Soaking in hot water will activate the shrinkage of the knit stitches and shrink your sweater evenly.

How do you shrink a coat?

Winter coats and jackets tend to become too loose after a few years. To readjust them to your figure:

• Wash your coat by hand or in the washing machine on a wool cycle at 30°C.
• Add 2 or 3 tennis balls to the drum to massage the fabric.
• Dry it flat, without stretching or hanging it.

The tennis balls will activate the felting of the wool and the shrinkage of the fabric during washing.

How to shrink a T-shirt?

Cotton T-shirts tend to stretch and lose their shape over time. To shrink it by one size:

• Fill a basin with hot water and half a glass of white vinegar.
• Immerse the T-shirt and leave it to soak for 15 minutes.
• Rinse with clean water.
• Spread the T-shirt out on a towel and stretch it slightly so that it returns to its original shape when dry.

The vinegar will cause the cotton fibers to shrink. This traditional remedy is an easy way to shrink a T-shirt.

How do you shrink a scarf or neckerchief?

Scarves, neck warmers, and loosely knit shawls often tend to stretch over time. To restore them to their original size, pour half a glass of vinegar into a basin of lukewarm water. Immerse the scarf or shawl and leave to soak for 20 minutes. Carefully remove the fabric and lay it flat on a clean towel without stretching it. Leave to air dry. The vinegar will activate the shrinkage of the knit. Repeat the process if necessary to gradually shrink your scarf. This simple manual method gives good results.

Tips for shrinking your clothes according to their material

Shrinking cotton clothes

Cotton is very elastic and shrinks well with the heat of the dryer. A short cycle at a high temperature is sufficient.

You can also soak your T-shirt, jeans, or other cotton garment in hot water with half a glass of vinegar added for 15 minutes. The vinegar will activate the shrinkage of the fibers.

Remove the garment gently and lay it flat on a towel. Stretch it slightly so that it dries without losing its shape. This simple technique will shrink your oversized cotton garment by one size.

Shrinking wool garments

Wool is a natural fiber that shrinks very well. Soak your wool sweater in boiling water for 30 minutes to shrink it. You can also wash your wool scarf or sweater at 30-40°C and dry them flat to adjust them.

Shrinking polyester garments

Although synthetic, polyester can also shrink slightly. Wash your polyester jacket or shirt at a maximum temperature of 40°C and dry them on a hanger to activate the shrinkage of the synthetic fabric.

Shrinking viscose garments

Viscose shrinks well when in contact with hot water. To readjust a viscose dress or blouse, wash it at 40°C and hang the garment up to dry while it is still damp. Gently stretch the fabric so that it dries without losing its shape.

Shrinking linen garments

Linen can withstand high temperatures. Wash your linen pants or tunic at 60°C to activate the shrinkage of the fibers. Gently hang the damp laundry, avoiding stretching it.

Shrinking silk garments

Silk is very delicate. To shrink a silk shirt or scarf, soak the fabric in warm water with half a glass of vinegar for 15 minutes. Lay flat on a towel to dry.

Shrinking microfiber garments

Microfiber is a synthetic material derived from polyester. To shrink a microfiber garment, such as a T-shirt, dress, or thick leggings, wash it in the washing machine at a maximum temperature of 40°C. Avoid high temperatures, which could damage the synthetic fibers.

Gently hang the garment while still damp after spinning to allow the fabric to shrink naturally as it dries. Do not stretch the garment, which should dry gradually to reduce its size. This simple shrinking technique is suitable for most synthetic materials.

Shrinking a garment without using a washing machine or dryer

There are certain techniques that can be used to shrink a garment by hand, without a machine:

• For cotton, soak the T-shirt or jeans in hot water with vinegar added for 15 to 20 minutes.
• For wool, prepare a bath with simmering water and soak the sweater for 30 minutes.
• Then lay it flat on a clean towel and stretch the garment slightly.
• You can also expose the damp garment to the steam from a pot of boiling water for a few minutes.

These manual techniques are very effective for naturally shrinking clothes that are too large.

Sewing techniques for adjusting the size of a garment

If washing techniques are not enough, it is possible to shrink a garment that is too large by sewing it:

• On a dress, skirt, or pants, you can tighten the side seams by partially unpicking them and re-sewing them with a narrower margin.
• On a jacket or shirt, pinch the fabric at the back and re-sew to reduce the width.
• Tuck in the armholes of a sweater by re-sewing them with an invisible seam.
• Take in the hems of pants, dresses, or skirts to shorten them.
• Add darts to a loose-fitting garment to cinch it at the waist.

With just a few stitches, an oversized garment can be transformed into a more fitted silhouette.
