It's Batgirl

As the heels crept closer, Selina was able to see the red hair flowing behind a cowl. She knew it had to be Batgirl. A few steps away, the figure became a silhouette, backlit by the city lights. Selina couldn't see anything other than the outline of her body, and was curious if she suffered the same fate. However, Batgirl stopped shy of a street lamp, just barely obscuring her from view.

"Selina and Harley, what brings you two out here this time of night? Judging by the looks of things, it seems like you two are doing a little public display of affection!" Batgirl giggled.

"Get your mind out the gutter, we need your help." Selina answered.

"Someone took our clothes!" Harley cried.

Batgirl had to some another laugh.

"Did someone finally manage to get the drop on you two? I can't believe it!" The red head smiled.

"Hey, they caught us sleeping." Selina interjected.

"Together?"

"I told you it's not like that! Ugh, someone stole our stuff while we were asleep. Harley came and found me at my place after I discovered everything I could wear was taken, save for this sheet."

"Wait, so was Harley naked when she got to your place?"

"Yeah, why?"

"Seems odd she would be covering up now when she was completely naked before."

"Hey, just because I was naked when I got to her place doesn't mean I left my place like that! I had a welcome mat in front of my door, and was using that until I had to climb up Cat Lady's fire escape." Harley explained.

Batgirl took a step into the light of a street lamp, and the two naked woman were shocked to see what Batgirl was wearing, or perhaps NOT wearing.
