Query: Toddler Muscle Robin looked cool with Adult Muscle Batman

Worn by my adult son (Batman) & grandson (Robin). Lots of fun & positive comments. Price was good but paid more because I waited to long to order (Price went up closer to Halloween, instead of down) plus paid extra shipping to make sure it arrived on time. Costume looked great but he would not wear the mask, too uncomfortable.
