I can't believe you guys could forget one of her most important items of equipment: the MEDALLION! There's probably a little crib note too to help remind her how to go through the "find the center of the light" speech.
Besides the Medallion, I'm sure she had:
a packet of Marlboros (Julia's too butch for Virginia Slims)
a matchbook from the High Hat Lounge
a hankie plus some tissue
a tiny bottle of Chanel No. 5
Dr's choice of prophylactics (you KNOW Jules was always prepared)
a fold-up rain bonnet
a .45 revolver (she almost used it during the Cassandra storyline, remember?)
Showing yet again that I spend WAY too much time thinking about my Favorite Redhead,
