How to Shrink Underwear

To shrink underwear properly, you need to properly wash your underwear in the washing machine’s hot cycle, or wash them by hand in hot water. Then, you’ll need to put the undergarments in the dryer to shrink them further if needed, before wearing them to the fit size you’re seeking.

Here’s a step by step on how to shrink underwear.

1. Read the printed label on the inside of your underwear to determine the material it was made of, as this step is important in determining if certain methods can work or not.

2. If the underwear is made of cotton, wool, silk,  rayon, or linen, it’ll shrink easily. If it’s made of nylon, polyester, spandex, it’ll need extra steps to shrink as needed.

3. Clean your underwear with water and laundry detergent by hand washing them thoroughly.

4. Put the settings on your washing machine to hot and long washing cycles, and the load size to small.

5. Turn on your washing machine and let it wash the underwear with hot water.

6. Take out the underwear and air-dry it, then check if it fits as you need it to.

7. You can repeat the process of washing the underwear in hot water if you need further shrinking, but then you’ll need to put it in the dryer instead of air drying it naturally, as this step provides the further shrinking.

How to Shrink Cotton Underwear

To shrink cotton underwear, you’ll need to clean them first with water and laundry detergent, then put the cotton underwear in the dryer that’s put on the hottest temperature for a 20-25 minute cycle. Make sure you’ve used the settings compatible with cotton fibers on your dryer.

Once the drying cycle is completed, try on the underwear after it cools down and see if it’s fit now.

You can repeat the cleaning then drying process one more time if the shrinking isn’t as fit as you’d like it to be, and it needs a bit more to be fit again.

How to Shrink Lace Underwear

You can shrink lace underwear by leaving them in a bucket filled with hot water and soaking them for 5-10 minutes. Then, you should add mild detergent and agitate the underwear with a spatula or a stick of some sort, then leave it for another 5-10 minutes in hot water. Once you get the lace underwear out and rinse the suds and water, you’ll have a fitter lace underwear.

If the underwear is not as form-fitting as you needed after it has dried out, you can repeat the same steps once again, and that should get the job done now.
