If you go for jeans that have a lot of bells and whistles, you may fall into the "fashion victim" category, Stacy warns. Don't fall for every new trend—skinny jeans and blue jeans tucked into boots may look good on your favorite celebrity, but not everyone can pull it off.
Stacy says patience—not fashion magazines—is the key to finding the perfect pair of jeans. "I feel terrible because women get so frustrated," she says. "They try on two pairs of jeans, and they say nothing fits me and they leave the store. You've got to try. And even if you don't get lucky after seven, if you get lucky after 20, it is worth it."
