No matter what the fashion trend is or the season, a man is loyal to a pair of jeans. Levi’s wrote the book on denim, no kidding. This years marks their 140th anniversary and the legendary brand published the limited-edition photo book Levi’s 501 Interpretations ($55), which features 501 images and is available at select Levi’s stores. The jeans are “defined by the people who wear them,” as Levi’s put it. Check out some of these great gift ideas for him available at Macy’s, Target and Barneys.
