6 Things To Do With Old Underwear:

1. Compost old underwear

If the underwear you want to get rid of is made from 100% natural materials (such as cotton, hemp fabric, bamboo, silk, or linen) and you have a home compost system, you can throw them there!

All you need to do is cut it into small pieces and throw them in your composting pile. Make sure to remove and cut off any tags, the elastic waistband, or synthetic decorations.

2. Repair your undies

It is always best to try to extend the life of your garments. 

If there is a small hole or something easily fixable – then consider repairing your undies! 

Or, if the elastic is worn out, you can wash the underwear in hot water to shrink them. You can re-attach broken bra straps easily or replace them entirely. 

Luckily, there are many tutorials online, so whatever the issue is, you can try to find a solution & fix them!

3. Upcycle old underwear

To get more out of old undies, you can:

  • Turn them into cleaning rags.
  • Use them to make dog toys.
  • Use them as stuffing for DIY pillows or stuffed animals.
  • You can cut them into strips if you have a garden and tie your tomato plants and other climbing veggies to stakes.
  • Cut in straps and use them in the bottom of pots when filling with soil. It will prevent the dirt from washing out through the holes. It will then eventually break down.

You can find many excellent and creative projects; do an online search for more ideas! 

4. Take your old undies to a textile recycling center

Research and see if you have a drop-off location for textile recycling near you. You can always contact your local council to ask whether textile recycling is available in your area.

If you don’t have available options nearby, you can send your old undergarments to the following organizations:

  • Council for Textile Recycling: Available in the US, Canada, a few International options. They also accept clothing, footwear, and textiles.

5. Donate clean and good-quality items

While not all items should be donated (especially ones with stains, rips, and loose elastic!), a pair that you’ve worn once, or never because you didn’t like them or they didn’t fit, can be donated to local charities or to homeless shelters where they can help someone in need.

Many traditional thrift stores (i.e., Goodwill and the Salvation Army) do not accept underwear donations, but some will take bras (check with your specific location first).

  • I Support the Girls: Available across the US. You can also mail items to them. Once you donate bras in good condition, they distribute them to women in need. 
  • The Bra Recyclers: Available in the US. Donate bras in good condition, as well as new panties. They partner with more than 100 non-profits around the globe and have already donated more than 4 million bras to women in need. 
  • Donate Your Bra: Available in the US. Accepting lingerie, bras, and swimsuits and distributing them to breast cancer survivors around the globe.
  • Free the Girls: Across the US. Donate unused bras to their drop-off locations or mail items to them. They work with those formerly involved in sex trafficking.
  • Local shelters: Check with local homeless shelters and ask if they accept bras or never-worn underwear for donations.

6. Sell unused & new underwear 

You can always consider selling bras or undies that you’ve never worn.

If you have entirely new ones that you didn’t wear because you didn’t like them or they didn’t fit – selling could be a fantastic option. 

In that way, you can make little extra cash for them. Some online second-hand platforms include:

Tips on making your underwear last longer 

Invest in high-quality undies 

By having high-quality lingerie, you’ll be able to wear them for much longer, and even though it may cost more, you will save money in the long run. Below, you can find my favorite high-quality undies brands. 

Air dry your underwear

The longevity of your undies depends on your laundry habits, too.

Laundering your undies correctly can help them last longer. If you look at the tag, they usually suggest washing them in warm water, by hand, and to air dry. 

Even if a set says you can put it through the dryer, it is better to never put them in there. Instead, wash at 60 degrees celsius, and then line dry your undies under the sun, as it is a great way to kill any germs that might be still on your clothing.

Use lingerie with care 

Some lingerie sets are fragile and delicate, and you can damage them accidentally by a slight wrong movement. So be careful and gentle with your undies to extend their life.

Should you throw away underwear? 

While you can dispose of your underwear in the trash can, it is quite an unsustainable option. Sadly, around 5 million kg of underwear a day ends up in landfill sites across the US.

Textile waste makes up an ungodly portion of landfill trash, and what’s worse, it takes up to 30 years to fully break down. That’s why choosing to recycle, donate, or upcycle old underwear or sell unused ones are all much better options than the trash.  

Can you put underwear in the recycling? 

If you have a Textile recycling center nearby, you can throw your underwear in there since it’s a piece of clothing, and it can get recycled. It is best to always double-check with the rules of the Textile recycling center first to make sure they will accept it.

What is the lifespan of underwear? 

There is not a specific time frame. It is good as long as your underwear functions correctly, the elastic is fine, and there are no holes. 

Once they become dysfunctional, uncomfortable, saggy, with holes – it’s time to get rid of that pair.

Can you donate used underwear to Goodwill? 

Most thrift stores cannot accept old underwear unless it’s in new condition. For example, Goodwill will take only not-used underwear in perfect condition.

  1. Sadly mine is going in the trash. No bins by anyone in my state. Several sites link to Parade which doesn’t work, and Knicky want me to open an account and buy stuff to get rid of mine. Lol that’s the point, I don’t want more I just want to get rid of mine. This is why people don’t recycle, it’s ridiculously difficult and off putting. I had thought I was recycling for the last 30 years only to find out it wasn’t really happening anyway. Just a guilt trip. I’m done. Let the corporations do their share.
