Where better to get Halloween costume ideas than from everyday celebrity outfits? Lady Gaga inspires a marshmallow costume with her 2015 VMA outfit. Amber Rose and Blac Chyna look like walking graffiti while Miley Cyrus looks like a futuristic lady Robocop. We also take a look at Erika Badu, who dons hat that looks straight out of Willy Wonka's Chocolate Factory. All great ideas for a unique costume this Halloween.
