Pharrell Williams' wedding to Helen Lasichanh (lucky!) this weekend in Miami was star-studded and check-tastic. Busta Rhymes and Usher performed a mini concert, Terry Richardson took time out to point his camera lens at something other than Miley Cyrus, and Robin Thicke is rumored to have performed too. The choice of outfit for the bride and groom (his a red check two-piece suit, hers a voluminous gown in classic blue and green tartan) took this season's trend for all things tartan into the stratosphere. If you're not digging on kilts and flannel shirts already, check out our checky faves below.
