While meeting up with friends for lunch in LA, Nicole Richie showed off her effortless Summer style in a black silk Winter Kate dress — here is the maxi version ($289). We love the subtle, lingerielike lace-trim detail up top and how the longer hemline balanced out the sexy factor. Nicole then completed her all-black look with exaggerated cat-eye sunglasses, her go-to Balenciaga bag, and tan strappy flat sandals. Next time you're having lunch with your girls, sport Nicole's exact dress or this similar but shorter Marc Jacobs lace-trimmed satin mini ($209, originally $695). To add a pop of color, ditch the tan sandals for something bright.
