Played a wedding yesterday. Keyboard for the ceremony in a park in Bluffton SC and then DJ on the deck of a restaurant in Hilton Head (Both the Bride and Groom work there)
I wore Black pants and shirt and a burgundy tie with a keyboard on it. When people started arriving for the ceremony I knew I wasn't in NJ anymore. Some were dressed appropriate but some had jeans and sweatshirts on. Sorry but thats a bit too casual for me, even in the laid back South.
Post above said it, "be one step above" but who knows theses days.
