Here is my Robin cosplay I debuted at Comic Media Expo 2015 in Mesa, AZ. The cosplay was partially made. The homemade parts consist of the Mask, the cape, and the belt. Parts I had to buy consist of the Vest, the patch (I sewed onto the vest), black undershirt, black tights, and boots.

Super easy costume if you know how to hand-sew. I love this cosplay, due to the fact it's super easy to just throw on for spontaneous cosplay. No prep work involved.
