I don't have the privilege of being able to use my husbands jeans (we're just not the same size). I wanted some perfect boyfriend jeans that don't look brand new, and this is how I went about it:
I bought pretty basic boyfriend jeans from Old Navy; there was a little fading on them and some "scratched" surfaces, but not really enough wear and tear for me.
I made cuts in the fabric with an X-Acto knife, and started picking away the small pieces of thread that were crossing the cuts.
I took out a back pocket.
I dipped about 2 inches of the jean legs into some Clorox Gentle Care Bleach. After they had started fading a bit I added water so the bleach-water-mix rose about an inch, and after a while I added more water etc, until the bottoms of the legs had gotten a bit of an ombre bleach on them.
I spread out some bleach, with the help of a brush, onto the ripped areas as well as above and below it. If you want the bleach edge to be less obvious, brush on some water first around the area you're thinking about bleaching; that'll dilute it a bit.
Note! I put some parchment paper inside the legs of the jeans so that the bleach wouldn't go through to the other side.
