Nicole Richie seems to be loving the Springtime weather in LA this week, which meant another flowy shirt coordinated with her favorite pair of short denim shorts yesterday. Wednesday afternoon she enjoyed a casual lunch with Jennifer Meyer before changing into a floor-length Missoni dress for the store's grand opening party with Rachel Zoe in Beverly Hills. She didn't sport any green in her wardrobe for St. Patrick's Day, but luckily her eyes got her off the hook from anyone wanting to hand out pinches. Nicole also kept her hair done up tight for a stop off at the salon accompanied by a few of her guy friends.
