Nicole goes girlie-rocker with a cool black jacket and sweet white dress—we say, her hair could use some softening and taming as well.

Nicole channels her inner geisha with this kimono-style look at the Celebration of Creative Minds party. Creative, indeed.

Nighty Night
Whoa! Nic's wearing a navy blue slipdress to promote her Winter Kate collection in L.A., but maybe this slinky number is better for the bedroom.
