I love thrifting Levi's and turning them into shorts when they're not long enough for me!
I usually just trim them about 3 inches from the bottom of the pockets and shorten if I need to! You can use a razor, scissors, or a box cutter for distressing them. :) I found this Pinterest tutorial as well.
Side note: If you have not tried Coffee Bean's Nitro Brew, you should! It's delicious. :)
