Halloween is right around the corner, but if you're still in search of the perfect costume, you're in luck—we have gathered the best celebrity Halloween costumes to kick-start your All Hallows' Eve style inspiration. Some celebs make dressing up a family affair: In 2012, Sandra Bullock and son Louis dressed up as Toy Story characters (pictured, left), while Jessica Alba and her clan suited up as the cast of Pixar's The Incredibles. Meanwhile, stars like Martha Stewart and Blake Lively (pictured, right) prove that they take prepping for costume parties just as seriously as dressing for a red carpet event by pulling out all the stops. Whether you choose to dress up solo or with a group, we're here to help you find some inspiration. Click through the gallery to see celebrities like Gisele Bündchen, Kim Kardashian, and Stacy Keibler dressed to the nines—and we’re not talking ballgowns and diamonds (only the Ellen DeGeneres spoofed version!), we’re talking $2,000+ wigs, Medusa headpieces, and seriously spooky contact lenses.
