I've been wanting to make a solid Robin costume for the longest time now. I've been working on/off putting pieces together, deciding whether I wanted to be Dick Greyson or Tim Drake (harder than it sounds), and most importantly making it seem as real as possible.
I had smoke bombs in the front right pouch, 6 batarangs in both the 2nd right/2nd left pouch, and an expandable staff (2 expandable batons welded together). I had several gadgets, even a lighter (belt buckle) haha. I had a lot of fun with this costume.
