Theory’s “Marah” ($395) is an airy silk dress with a flattering drop-waist silhouette. The small star print is cosmically sweet and the see-through black silk is beautifully alluring. Pile your hair up high on your head and let a few tendrils come twirling down. This will allow you to display the keyhole button closure, a beautiful touch, at the back of the dress. Let simple black pumps finish the look.
