I noticed that she was chewing gum whilst she stripped down to her saucy underwear and that she was wearing stockings and suspenders. If you going to entertain a male audience like she did in this particular film you have to wear the appropriate uniform and underwear etc
I see she has stripped off in at least one other film, but what makes this is the stockings and suspenders and she's chewing gum as if she's bored stiff!
