Baring just the right amount of skin — and showing off her brand new pixie haircut — Rihanna hit all the right notes in a crisp, custom white floor-length gown by Adam Selman and nude sandals. The fitted number, complete with a dramatic tie-front cinch, hugged every curve, allowing for her svelte figure to take all the credit. Lest we forget, the dress's revealing back cutout was also adorned with sweet tied-knot details at the shoulders and the lower back. Unlike some of singer's more daring red-carpet appearances, this one appeals to a fresh, minimalist sensibility. How do you think she did?
