Grab some gloves, a bottle of Clorox and start dipping. Yep, I mean the bottle of Clorox bleach that you use for your laundry.
I had a couple of high waist vintage shorts that I found at the thrift for less than a dollar. I wanted to give them some attitude so, I decided to bleach them. BUT, first i had to cut them up lol I tried them on and measured how short I wanted them and used my scissors to cut them to the desired length. I also made random cuts across the legs and pockets to give them a more destroyed look.
After rinsing all of the shorts, I threw them in the washing machine with a little bit of detergent. Then into the dryer to give the fringe/fuzzy.
Have fun and be creative, you can even try twisting for a tie dye print.
