I love swapping my clothes! As I've been losing weight (and occasionally gaining it back unfortunately), I've had to change up my wardrobe quite a bit. It would have cost me a fortune, had I not discovered Swapstyle.com years and years ago. It was actually in Self magazine, if I remember right.
Since then I've joined rehash.com as well, but it seems like there are mostly US and UK people on there. That's not a problem, but for just ordinary clothes I don't want to have to ship them around the world.
Anyway, it's still a great way to save money, and keep looking great!
