16 Demi Lovato Costume Ideas That Will Make You Cool For Halloween

Demi's "Cool For the Summer" was our Summer 2015 jam. The playful pastel outfit on her single cover was all we wanted to wear that season. We loved the look so much that we're still thinking about it a year later, and we're going to take advantage of Halloween to relive it.

• What to wear: A sexy pastel one-piece swimsuit and a colorful faux fur coat. Accessorize with heels and bright sunglasses. Keep your makeup dewy, and don't be stingy with the bronzer.
• How to act: Like you're too cool for wherever you are. Yet you're there to grace everyone with your sexy outfit.
