In my urgent need to get Summer clothes, I've recently turned a pair of pants into a pair of shorts just by cutting off the excess fabric on the legs.
I really didn't like the original piece. It fitted me pretty well, but legs were too short for me.
When I recovered them from my bin (where it stood for too long), it was all pinned in order to turn them into skinnys but I wanted a new pair of shorts, and that's what I made.
I first thought about adding a contrast fabric to the seams, but then I gave up on that idea. Just cut. And that's it... I like to unfinished look... always have... I have been wearing them a lot ever since, they are comfortable and easy to match. =)
