It’s supermodel Claudia Schiffer’s 42nd birthday today! Ever since we first got to know her as the original face of Guess jeans, the German-born beauty became a catwalk fixture on the runways of Versace, Valentino, and Yves Saint Laurent and also tried her hand at acting, like in Love, Actually and Zoolander. In honor of Claudia’s latest birthday, take a look back at her transformation over the years in the gallery.

We love that Catherine Middleton famously does her own makeup, and our readers agree—this was InStyle’s most-pinned photo of the week! Duchess Kate is a fan of Bobbi Brown’s products, and we caught up with the makeup guru to get the scoop on how to score Middleton’s princess look. “Catherine has the perfect balance between classic and modern,” Brown told InStyle.com. “Her bold brows frame her face, while a swipe of gloss and pop of pink blush give her a healthy glow.”  Show your Kate love by repinning it yourself, and tell us what else you’re loving by repinning, liking, or commenting on any of our 57 stylish boards.
