Oh, this is a tough one!

I've always thought Danielle was gorgeous either way, but since I love tits so much... I'd pick the topless one. Though I'm sure if she wore the clown costume with a mask and a knife, I'd probably be able to get off on that too.

The One From Roseanne.

As iconic as her in the clown costume is, my dick says topless. I'm not crazy about Rob Zombie's remake, but she's a highlight of that movie for me.

You can see her as an adult in the clown costume as she seduces Adam Green in the Holliston TV Series episode 'Halloween Girl'
