Who: Rachel McAdams.

When: Wednesday, May 4.

Where: A screening of Sonic Sea in New York City.

What: A mulberry chiffon and velvet Vivian Chan top and skirt.

Why: As if we needed more evidence that dark, purply tones play to McAdams's strengths, this Vivian Chan design offers it in droves. With a sweet pointed collar, short sleeves, and A-line silhouette, the matching separates make for a demure post-Met Gala appearance — but the alternating sheer paneling gives the look a bit of edge. With looks like this, velvet is poised for quite a year.
