A casual observation
"Good morning" said Harley, bright as always.
"You're in a good mood today" The Joker noted.
"And how would you know that? I haven't said anything."
"You're wearing that jumpsuit." He smiled "I can tell a lot about you before you say a word, us men are a lot more observant than women give us credit for. Like I can tell today you are hopeful and self confident, going out on a pull? Or meeting up with some pre arranged date. I know this because your zipper is on your front. I already knew you liked your men on top, so you must have your back down, so rather than have him uncomfortably prise his way to get to your back; you wear the one with the zipper on the front. Nice and easy.
"I can also tell your not wearing any underwear." He added. She crossed her arms sharply over her chest, a pale blush coming to her face. "You can tell?" she asked. "Not by your appearance, by your walk. You see, when you walk you move your hips more, because you think you bust will not attract as much attention, you don't even know your doing it. I would notice this, I see you every day, but your new boyfriend wont notice until he pulls that zipper of yours." He flicked it idly. "Of course you're wrong, there is no difference to look at, lucky for you that jumpsuit holds your figure marvellously." She smiled at the complement.
"I can also tell you're going to a party, because that jumpsuit is rain proof and you are wearing your gloves. It is fancy dress party? Yes, or you would be wearing civilian clothing." He leaned close to her. "But tell me, do you still want to go?"
