DC Showcase: Catwoman

Tropes used in DC Showcase: Catwoman include:

Author Appeal: Written by Paul Dini? That explains so much.
Absolute Cleavage: Occurs when Catwoman zips down her catsuit.
Badass Normal: Catwoman of course.
Clothing Damage: Catwoman's suit receives a pretty hefty helping of this by the end.
Continuity Nod: The art style is nigh-identical to that used for the Batman: Year One animated film, albeit based on a more modern setting. Holly Robinson appears at the end of the film, looking exactly like her Year One design.
Dance Battler: Catwoman briefly demonstrates this in the club.
Dirty Harriet: Catwoman poses as a stripper in order to get close to Rough Cut.
Fan Service: Probably the highest amount out of all the movies and shorts so far. For one thing, a good portion of the first half takes place in a strip club (with even Catwoman herself getting in on the act, if only as a ruse).
For Halloween I Am Going as Myself: Catwoman briefly pretends to be an exotic dancer in order to get closer to Rough Cut.
Hero Stole My Bike: After Rough Cut manages to escape from the club in a getaway car, Catwoman notices a lone biker outside the entrance. She seductively walks up to him, grabs his collar, and leans in as if to kiss him... then pushes him over, takes his bike and drives off.
She Fu
Show Some Leg: The entire point of Catwoman's "dance".
Under the Truck: Catwoman slides her stolen motorcycle under a truck while chasing Rough Cut. For bonus style points, the truck is tipping over at the time.
Victoria's Secret Compartment: Selina retrieves her whip and a golden cat collar from inside her suit by way of her undoing her top. This is quite impressive considering just how tight we see the suit really is.
