In case you were thinking that sequin dress in your closet should only be worn on New Year's, Selena Gomez has another idea. The singer stepped out at Billboard's Women in Music event on Friday, with a longline vest layered up right on top of her sparkly Rodarte dress. The effect is unexpectedly sophisticated - a fresh take that defies holiday-dressing cliches, with a structured bag, tights, and an understated choker to finish it all off. In total, it's a look that's got us thinking how very easy it would be to to add the same add-ons to that little sequin dress that's been hanging in our closet. Just read on to see why, then shop our picks to do the same.
