Dad wore a black cape and twisted blue and silver pipe cleaners to his fingers for sith lightening.
Zoli wore a white t-shirt with the sleeves removed and widened. I sketched on the trooper armor (a throw back to the old R2 costume from his first SW halloween). The helmet is a cake package lid cut and covered in white hockey tape, a small black ribbon and white ribbon to keep it in place (for the most part).
Vader was fleece pants (x2 as potty training is still in progress) a black long sleeve t-shirt as the base. A cape was made from a small rectangle of sheer black material held in place by a snap tacked to each shoulder for easy detachment throughout the day/night. The panel was made from foam and a few pieces of red sparkly pipe-cleaners. The 'helmet' was a simple fleece hat with a frill strategically attached. The ensemble was completed with a build-a-bear lightsaber complete with sounds!
Mom and baby were in an old white maternity shirt with death star and tie fighters drawn on with a sharpie.
