Batman Robin Costume?

I'm not sure what your question is. The Robin in the picture you linked to is Damian Wayne, so just copy the picture. I guess the most important differences are that the first two Robins, Dick and Jason, had bare legs and short sleeves. The third Robin Tim wore full-length tights, probably for extra protection because Batman was worried he'd let Jason be killed. Damian also is completely covered. The most noticeable differences with Damian's costume are the very realistic boots with laces. Other Robins wore slip-ons, the first two had "pixie-boots" as Batgirl called them and Tim had higher boots. And Damian has a hood in his cape. The hood is probably the most important aspect of the costume if you want people to know for sure it's Damian and not Tim
