Now this is the costume for the guy that just doesn’t really care, however, he promised his friends he’d dress up for Halloween. Technically you’re in full R2D2 costume, it just happens to come in a comfortable hoodie form. You can also get the Sidekick Hoodie if you’re a big fan of Robin. The Robin hoodie is still in stock for $42 through Etsy. However, as of now the R2D2 one is completely out of stock.
