Pharrell Williams' Miami wedding to Helen Lasichanh was star-studded and checked out. 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 rumoured to have performed, too.

If you haven't embraced kilts and flannel shirts already, check out our favourite check pieces below.
