Looking radiant in a white feathery evening dress with plunging neckline, the 28-year-old R&B singer stole the show with her 1960s Motown revival and Diana Ross-inspired style.
Hilson recreated the signature Supremes look with her hip-hugging glamorous gown, blonde bouffant wig and frosted silver eyeshadow. Not to mention the heavy geometric black eyeliner -- a resurging trend that has marked many red carpets and runways lately.
