Last week at the premiere of film Spring Breakers in L.A. good girl gone racy, Selena Gomez looked all grown up in a plunging red dress. The floor-length number featured this season's favourite peek-a-boo detailing on the waist and neckline but was made slightly more modest with sheer, diamanté decorated inserts. The deep neckline, delicate belt and floor-sweeping length worked to lengthen the singer's petite frame and the rich scarlet hue complimented Selena's complexion perfectly. Teamed with a classic black patent clutch bag, gold drop earrings, a cocktail ring and dark nails this is Hollywood glam at it's very best. Follow in Selena's fashionable footsteps and invest in a long red dress for your next special occasion and just add a few choice accessories and tumbling curls for a red carpet-worthy look.
