Emily Blunt left a West Hollywood hair salon showing off her cool Summer style in gray cargo pants and a floral scarf. We saw 10 celebs working their Summer scarves, and now Emily shows us yet another way to showcase your lightweight scarves. She completed her look with a white top, gray ankle booties, a dark red shoulder bag, and plastic aviators. Without her scarf, Emily's look would have been too colorless, but with it, it got a major dose of fun. Next time you're getting dressed in a neutral outfit like Emily's, remember to reach for your Summer scarf to take your outfit to the next level.
