Jazwares Darth Vader Child Costume Black/Gray/White

Don't Underestimate the Force
Those foolish Rebels are at it again. They think that they can stand up to the Dark Side, but having been a Jedi in the past, you know what a threat these brave but misguided souls can be. It's going to be up to you to conquer their forces, shoot down their X-Wings, and prepare the way for Emperor Palpatine's takeover. Nothing's going to stop you from carrying out your plan. So long as there isn't any other tyke dressed up as Luke, anyway!
Product Details
Are you doubtful that this officially licensed Darth Vader Costume for Children will be the best costume ever? Your lack of faith is disturbing. The jumpsuit costume is printed all over with cool graphics to make it look just like the Sith Lord's famous armor. A control panel is printed across the chest above the attached belt. Boot covers secure under your feet, and a short cape attaches to your shoulders. The plastic Vader mask completes your journey to the Dark Side! 
Now You Are the Master
Grab your red lightsaber and practice your deep, scary breathing because this costume will have you ready to lead the Empire's Stormtroopers to victory! Either that or it will help you lead a group of friends dressed as Stormtroopers and other Star Wars characters to find a lot of Halloween candy. That sounds like a much more fun mission and doesn't even require a planet-sized killing machine for success. Everybody wins.
