Our adult 300 costumes are designed in honor of the film 300, starring Gerard Butler. 300 is a Roman era movie based on the book of the same name by Frank Miller, and tells the story of the famous Battle of Thermopylae. In our adult 300 costumes, you can reenact the movie or simply enjoy bringing back to life a period of time when the sword was as mighty as the pen. Pair your Spartan adult 300 costume of Leonidas with our Roman Empress or Spartan Queen Gorgo 300 costume for adults and the two of you will be the hit at any Halloween party or costume event. Our adult 300 costumes feature authentic, licensed costumes and deluxe versions suitable for stage performances. Your night will be as victorious as any Spartan battle when you choose one of our adult 300 costumes, and these costumes are a perfect alternative for toga style parties, too, giving you an edge over your sheet-wrapped counterparts.
