If there's one thing we can count on every Halloween (aside from near endless supplies of candy), it's that celebrities will fully embrace the holiday. And, of course, Halloween 2015 was no different. This year's crop of celebrity costumes may have been the best yet, with everyone from Jessica Alba and husband Cash Warren to Lady Gaga's dog and Viola Davis's daughter getting in on the action with show-stopping getups. And luckily Instagram has become the gift that keeps on giving, with our favorite stars taking to the photo-sharing app to share 'grams of their multiple costumes. Keep reading to see more of the best celebrity Halloween costumes.
