Mens suiting has been done before — hello, Annie Hall, and Julia Roberts in that Golden Globes outfit — but Olivia Palermo gets the proportions all right in her casually sexy suit. She pairs skinny cropped pants and a boyfriend blazer over a white blouse and loose tie, but adds feminine touches like the jeweled tie clip and clear clutch, and sexy leopard pumps. The overall effect is casual, fun, surprisingly sexy. The notion of menswear for evening just became a lot more attractive.
