Pajama dressing graced the runways at Marc Jacobs and Louis Vuitton while celebrities like Rihanna, Jessica Alba, and Rashida Jones took the look to the red carpets. For the average person, attempting the same bedhead-chic vibe can be tricky. You could quickly wind up looking sloppy and shapeless. To properly achieve that relaxed effect while remaining polished, take a cue from the way this stylish show attendee has styled her pants. Rather than adding a heel as to "dress up" the outfit, she fully embraces the pajama and slippers look by adding a flat sandal. Recreate this outfit by first choosing a dark, patterned pair of silky trousers hemmed so they graze the tops of feet. Then add a metallic flat for shine, and finish off with a rich jewel-tone textured clutch. On top, you'll want to avoid busy patterns or anything boxy: instead, wear a simple fitted silk tank or tee to keep the silhouette clean.
