All eyes are on spring’s upgraded denim—and no one does it better than Alexa Chung for AG Jeans. Take a cue from fellow It-girl, Jamie King and step out in the line’s embroidered shirt. With its utilitarian shape and girlish embellishments, this makes for the perfect lightweight cover-up. Balance the boxy with a sultry leather mini and graphic extras. Our picks: Roland Mouret’s oversized shades and Pierre Hardy’s cutout boots for instant city chic.
