When It Comes to Sexy Halloween Costumes, Jennifer Lopez Is an Endless Source of Inspiration

In this music video, Jennifer Lopez wore a metallic bodysuit so good she had to wear it again to perform the song at Wango Tango.

• What to wear: Nothing could be more perfect for Halloween than a metallic spiderweb bodysuit. If you can't find a similar piece, opt for a nude bodysuit and use metallic paint to create the design.
• How to act: In the spirit of "On the Floor," make sure you get down on the dance floor. Let loose, and don't be afraid to shake your hair in everyone's face.
