How to Unshrink Clothes: Proven Methods to Salvage Your Wardrobe
Restore shrunken garments at home using fiber-relaxing methods and gentle reshaping.
How to Unshrink Clothes: Step-by-Step Laundry Hacks
Watching a favorite sweater or shirt come out of the wash three sizes too small is a universal laundry horror story. Fortunately, you don’t need to say goodbye to your favorite shrunken wardrobe pieces. With practical household ingredients and a little patience, you can often unshrink clothes and bring them back to a wearable size. This comprehensive guide will show you exactly how, covering everything from common causes of shrinkage to tailored solutions for various fabrics—and how to keep clothes from shrinking in the first place.
Why Clothes Shrink: The Science Behind Fabric Shrinkage
Most clothes shrink due to heat, moisture, and agitation during washing and drying cycles. Natural fibers like cotton, wool, and linen are particularly vulnerable. Here’s what typically causes shrinkage:
- Hot water or high heat in the dryer: Fibers contract when exposed to high temperatures.
- Agitation: Excessive movement can further compress fibers, especially in delicate fabrics.
- Moisture: Water causes natural fibers to swell; as they dry, they can shrink back—sometimes too far.
- Poor laundry practices: Ignoring garment labels and mixing fabric types increases the risk.
How to Unshrink Clothes: The Ultimate Step-by-Step Guide
Follow these carefully curated steps, backed by laundry experts, to help your garment recover its former glory. Most methods work best on natural fibers but can help synthetic blends too.
General Unshrinking Method (Works for Most Fabrics)
- Fill a basin with lukewarm water. Make sure the water is just warm to the touch—not hot.
- Add a gentle fabric relaxer. Pour in about 1/3 cup of hair conditioner or several squirts of baby shampoo. Stir to mix well. These products help relax the fabric’s fibers.
- Soak the garment. Submerge your shrunken clothing and let it soak for 10–30 minutes. This allows the fibers to loosen.
- Gently squeeze out excess water. Do not wring! Instead, lightly press the garment against the basin’s side or between your hands.
- Roll in a towel. Lay the garment flat on a clean, dry towel. Roll up the towel with the garment inside (like a jelly roll) and gently press to blot out additional moisture.
- Lay flat and stretch. Place the damp (not dripping wet) garment on another dry towel on a flat surface. Using your hands, gently tug and reshape the fabric, focusing on the areas most affected by shrinkage.
- Air dry flat. Lay out flat to dry naturally. Avoid hangers, which can distort the shape, and do not use heat.
Fabric-Specific Strategies
| Fabric Type | Best Unshrinking Method |
|---|---|
| Cotton | Soak in lukewarm water with hair conditioner, stretch while wet, lay flat to dry |
| Wool | Soak in cool water with baby shampoo or conditioner, stretch gently, block on a towel, air dry |
| Cashmere | Steam gently and stretch, use towel blocking technique, air dry |
| Denim | Dampen, stretch waistband/legs by hand, wear while damp for reshaping if possible |
| Synthetics/Blends | Gentle soak and stretch may help, results vary |
Unshrinking Wool Garments (Sweaters, Scarves, Hats)
Wool is notorious for felting and shrinking, but it can also recover if approached gently.
- Fill a tub or basin with cool water and a tablespoon of baby shampoo or hair conditioner.
- Submerge the garment and soak 20–30 minutes.
- Press (don’t wring) out water.
- Lay flat on a towel, roll, and gently blot excess water.
- Lay out flat and gently stretch to original proportions. Pin edges to the towel if needed to “block” the shape.
- Allow to air dry completely.
Note: Some wool pieces may not fully regain their original size, but this method maximizes your chances.
Unshrinking Cotton Clothing (T-Shirts, Dresses, Sheets)
Cotton responds especially well to conditioner or baby shampoo soaking and gentle stretching.
- Soak 25–30 minutes using lukewarm water and a generous amount of hair conditioner.
- Focus your stretching on shoulder seams, sleeves, and body length that shrank the most.
- Let air dry flat; avoid hangers and heat.
Unshrinking Jeans and Denim
Denim can be tough, but is sometimes salvageable using moisture and manual stretching:
- Mist jeans with lukewarm water or soak waistband/legs for a few minutes.
- Hold the waistband and knees, then gently pull to stretch the fabric lengthwise and at the waist.
- Optionally, wear the jeans while slightly damp for better form recovery.
- Air dry flat or on a straight line—avoid hangers if pockets and seams are heavy while wet.
Caring for Other Delicate Fabrics
- Cashmere: Use gentle steam (from a handheld steamer or iron with steam setting), lay flat, and block into shape by pinning to a towel. Avoid soaking, which can distort the knit.
- Blends & Synthetics: Mild shampoo/conditioner satins blend fibers. Some fabrics can be coaxed bigger but may not fully revert.

Expert Tips for Success: Getting the Best Results
- Be patient: Gradual, low-force stretching yields better, longer-lasting results than aggressive pulling.
- Use your hands, not tools: Avoid tools or hangers during stretching; fingers provide better control.
- Block knits: For sweaters and knits, lay flat and pin into desired measurements while drying.
- Focus on key areas: Target areas that need the most stretch, like sleeves, chest, or hemline.
- Repeat if necessary: For more severe shrinkage, repeat soaking and stretching process several times, letting garment dry fully between attempts.
Laundry Mistakes That Lead to Shrinkage
Prevention is just as important as knowing how to unshrink. The most common mistakes include:
- Washing on hot cycles instead of cold/delicate settings.
- Tumble drying clothes at high heat.
- Ignoring care label instructions.
- Overcrowding the washer or dryer, leading to excess friction.
- Using standard detergents for delicate or specialty fabrics.
How to Prevent Clothes from Shrinking
- Always read garment care labels and follow washing/drying recommendations.
- Wash clothes in cold water to prevent fiber contraction.
- Choose air drying or the lowest heat setting on your dryer.
- For delicates, use mesh laundry bags and detergent sheets designed for low-temperature use.
- Avoid wringing or twisting garments to remove water.
- Reshape items while damp and lay flat.
Laundry Experts’ Additional Advice
- Try Vinegar & Conditioner: For tougher cases, mix one part white vinegar with two parts lukewarm water, add a dash of conditioner, soak, and stretch as you would with the general method.
- Patience is key: Sometimes full recovery isn’t possible, but improvement almost always is.
- Store carefully: Fold knits and sweaters instead of hanging them to keep their shape.
Frequently Asked Questions (FAQs)
Can I unshrink any fabric?
You can often recover most of the lost size from natural fibers like cotton, wool, and linen. Blends and synthetics are less responsive, but gentle soaking and stretching may help.
How many times can I try to unshrink a garment?
You can repeat the process several times if needed. Be sure to allow garments to dry fully between attempts to avoid overstressing fibers.
Will my clothes go back to their exact original size?
Most garments regain much of their lost size and shape, but severe shrinkage or felting (especially with wool) may not fully reverse. Results are best with mild to moderate shrinkage.
Do I need to rinse out conditioner or shampoo?
No, if you use just a small amount. Simply press out excess water. Rinsing may stiffen the fibers again, so it’s usually skipped for unshrinking.
What if my clothes shrink every time I wash them?
Double-check your laundry routine: switch to cold water, skip the dryer, and always follow care labels. Consider air drying and specialty detergents for delicates.
Summary Table: Main Unshrinking Methods
