Batman and a Robin Costume

My son wanted to go as Batman and I do not like buying costumes. So I ended up making his entire costume and making his sister a matching robin outfit. The batman mask was duct tape, cardboard, and paint. A garbage bag was cut into the cape, and I drew a paper emblem and taped it onto a grey shirt. :-P. The robin is a sewn monstrosity with fabric feathers glued all over and a mask altered to be a bird beak.
