It's time to turn your hangers around!

Alright everyone, have you seen the thing on Pinterest about turning the hangers in your closet around? Then, after a year, if you have any hangers still turned around, you get rid of those clothes. Well I'm going to try it out this year. I always think I'm going to wear something (or lose some weight and fit back into it), but then I don't. I'm making the commitment to get rid of anything I don't wear this year. What do you guys do to decide whether you keep your clothes or not?
