I have found that lately I have been having horrible luck when it comes to zippers. I mainly wear skirts and dresses and lately they seem to be snagging a lot or the zipper seems have widened and wont push together to close. It's so bad that I think I may have to take some of my favorite pieces to a tailor and see if I can get new zippers put in but since I have never done that before I was wondering if that was even possible? Some of my stuff is nice silk and I don't know if it could handle it. Any suggestions?
