The Piece: Gucci Double-Knot Dress

The Investment: $2,300

Why We Covet: When Chanel Iman wore this dress down the runway, we had two words: "yes, please." It's sexy, it's bold, the nude and orange color combo are fresh, and it's one of the highlight dresses from a really strong collection. The double silk satin fabric and bamboo tassel detail are ultra luxurious, but the dress isn't fussy. You can wear this to weddings, cocktail parties, and black-tie events, or you can throw a blazer over it to tone down the sexiness. This is a modern dress you'll wear for years.
