How do you make Sweatpants more Baggy?

To make your sweatpants baggier, you will want to wear them as often as you can so the fabric starts to loosen and give.

The fibres will contract as they dry by wetting your sweatpants, working against your end goal of having baggier sweatpants.

How can I Stretch my Sweatpants?

Before taking these steps below, I suggest you give up on this pair of sweatpants you want to stretch and instead buy a new pair that fits you perfectly. The work you will put into stretching them has a very high chance of rebounding back to their original size in very little time.

If your mind is set on the stretch, I will give you the best steps to succeed in this alteration venture of yours. Here is how to stretch sweatpants.

Soak and Stretch

By choosing this option, thoroughly soaking them will stretch the entirety of your sweatpants.

To start, you will want to have a basin big enough to submerse them with water in it. I suggest using your bathtub, kitchen sink or YETI Hard Cooler. May as well give it something more to do than hold your beers in the summer!

1. Soak

Soak your sweatpants in warm water with 15mL of baby shampoo. If you do not have baby shampoo, then substitute it with 15mL of conditioner, and if you don’t have then, then plain water will do. Let the pants stay fully submerged for 1 hour before you take them out and try to stretch them.

2. Hang after Soaking

Take out the sweatpants and do not wring them out. Instead, hang them dripping wet from a clothing line outside or drying rack inside. If you choose the drying rack, make sure you put down a towel to soak up the drippings. 

The weight of the water will pull on the fabric and stretch them out as they dry. This option will give you very little control over which areas of the pants will be stretched.

3. Stretch after Soaking

Take out the sweatpants and lay them across your drying rack or on a flat surface. Take each hand and pull in opposite directions on the areas you want to be stretched. This option will give you more control of what happens to your pants compared to hanging them.

4. Sit in a Bathtub

Instead of submerging the sweatpants by themselves, this option will have you putting them on and wearing them in the tub. Fill your tub with warm water and sit down for 15 minutes, making sure all of the fabric is underwater. 

Keep the pants on when you get out and wear them until they are dry. It is best to do this method on a summer day when you can go outside and let the sun help speed up the drying process.

Spray and Stretch

Choosing this option will give you more control of the area you want to stretch and take less time from start to dry and ready to wear.

1. Spray with Bottle

Hang up the sweatpants on the back of a chair or drying rack and fill a spray bottle with warm water. Spray the areas you want to stretch until they are soaked. 

2. Pull with Hands

Once the area is fully saturated with warm water, put down the spray bottle and grab the spot you wish to stretch. Pull the edges of the application site, having your hands pulling away from each other.

3. Dry

After stretching all of the tight areas, hang them up on a drying rack (line dry), clothes hanger, dry flat or the back of a chair in the kitchen. The main focus is to dry them without using a dryer. Wait until they are fully dry before you put them on to test your work. Make sure you know how to use a dryer properly before any of these steps.

You may need to repeat the steps until you get the exact stretch you want.

And to make sure you do not ruin the work you put into stretching your sweatpants, put them away properly after they are dry.
