How to Wear It: The top—whether it's off-the-shoulder or more fitted—needs to come in at the waist. Nothing should be loose or untucked.
If You're Short: Make sure the hem doesn't dip below the knee, or you risk looking "too flamenco dancer," says Adam. "The rule of thumb when it comes to hemlines? Petite women look best in skirts that hit just above the knee; taller women should wear knee length or longer." And no matter your height, choose skinny heels.
If You're Tall: Have fun with patterned tights and seamed hose. "Think Sophia Loren in Rome."
What to Avoid: If you want to wear a jacket, make sure it ends around the waist, no longer. As for shoes, avoid any style that ties around the ankle (too cha-cha!), boots, and wedges.
