Ariana Grande Worked It in a Red Dress at the 2013 American Music Awards [RED CARPET PHOTOS]

Ariana Grande sparkled in a floor-length scarlet dress on the 2013 American Music Awards red carpet. It's not often that the singer opts for something this long, but we love it! Since there is a lot of sparkle going on in the sequin-covered gown, we like that Ariana kept her makeup and accessories minimal. Her black clutch is the perfect accent to the trim on the dress.
