This was my first jean jacket. The shoulders were HUGE (shoulder pad -esque) so when I got a jacket that actually fit, I became determined to do something cool with the old one. So I cut the sleeves off, took the sides in to make it more fitted, sewed on the back panel and the collar, colored the worn parts of the jacket with semi-permanent hair dye and washable markers, and finally threw some pins/random metal stuff/bracelet on there. I only safety pinned the bracelet on, as I'd like to be able to wear it sometimes.
A couple snips and a plain T shirt is transformed into a super cute vest!
