PLEASE HELP
Try selling them at ebay, etsy, or any online market possible, or if your town or city has a fleamarket you can go there too. Best of luck.
Garage sale would be your best bet. But if it's junk and doesn't work, you're not going to get much for it.
you might be asking too much money for the "junk" and you will rarely get anything for old clothes - donate them
eBay.
