Depends on the Gig,

Weddings have been known to demand a DJ, Student gigs T shirt and Jeans - But - as a Caller something that sets me apart form the band and the crowd so they (band and public) know where I am at all times!

I always pay homage to the god of beer vouchers (money) the public provide my access to the God so I have to show respect to them and their supply of it to me!
