This photo of Arielle from Lookbook put us in such a feel-good mood that we just had to share. It espouses one of our favorite fashion rules: if you can't have fun in your outfit, then what's the point? To be prepared for any number of spur-of-the-moment summer activities of your own, you've got to own a pair of tailored shorts and summertime wedges that can go from a dressy rooftop barbecue to an impromptu romp in a grassy knoll. Add to that a versatile striped tee and some major hardware that ties everything all together, and you're set for whatever warm-weathered whims come your way. Take a look at our picks from Refinery29 Shops to get the look for yourself.
