Give Her the Slip
A perfectly simple white dress is the canvas for a vibrant floral still-life (Tibi, $458). The result is the most comfortable party piece imaginable. The silk glides freely over the body, so it's as unrestricted as a nightgown; the tea-length hemline works with heels or flats (these, from Mia, could be the season's smartest buy at $59).
