Sometimes collecting photographs is also about collecting your favorite fashions. That said, in the world of collecting, style is more than just aesthetics. It can also be a helpful set of clues when you're trying to learn more about a given photograph, especially when it comes to dating and age. In this collection, we at HIP present our favorite moments in the America's history of style. We hope these images have something to teach you, not just about the pleasure of getting dressed, but also about how to pay attention to style in your own archival detective work.
