"I probably have a hundred little black dresses," admits Lucky accessories director Julia Kalachnikoff. "I’m especially drawn to styles with an A-line shape that feel a bit mod." Although she tends to keep to a mostly black-and-white palette, Kalachnikoff has a few secret weapons when she wants to add a little color. "Gold jewelry brightens everything," she says. "And a great scarf. They make even the simplest look instantly more interesting."
