Who says your neckline should have all the fun? While hair jewelry can be a risk, the simple gold chain Florence Welch added to her updo hit all the right notes. Welch's hairstylist, Nikki Providence, used Davines Defining Texturizer ($18; drugstore.com) to make the star's hair less slipperya must if you opt for a braided style.

Providence wrapped each plait across the top of the singer's head, and secured with hair pins before adding the final gilded touch.
