Jolene is dressing up as close to the catering service uniform as possible. She will also try to get a mock uniform for DJ SMOOV, too. White linen with painted on caterer logos?
Ideally a food service uniform that goes under a fancy pull-away talent costume top. That way she can wave away some security at the start with her obvious talent attire, and then hop into the food cart, rip off her pull-away costume, and be snuck out the service entrance. Then she can look like a food server once we're all in the pickup truck heading back, in case we're pulled over.
"Now what sort of concealer'll covers up your electronics, sweetie?" Helps apply make-up onto DJ SMOOV, looking like a make-up artist in case anyone pops in. "And any clothes or accessories you just can't live without? I got a backpack purse, and I know you'll want something afterwards."
"Ooh, that one's nice. Very evening. Every woman needs a little black dress. On loan for the tour?" Points out a pair or two of fashionable but sensible running shoes to be separated for the cart. "Just in case we gotta run, dear."
Slips into girl talk as she lets DJ SMOOV select extra clothes to stash away for our exit into her new life. It'll comforting to us and innocuous to eavesdroppers at the same time.
