Ever buy makeup and then realize it's totally wrong for your skin tone? Nikki Kinzer, professional organizer and owner of Take Control Organizing
, assures that it doesn't have to go to waste. "Any unopened makeup that is not going to be used can be donated to a local women's shelter or local high-school drama department. Rule of thumb: If you haven't used it in the last year, you won't use it!" In fact, she says, we generally use only 20 percent of what we have. When sorting, ask yourself: Do I use it? Do I love it? Do I really need it?
