Fantastic! Or, I guess it's more appropriate to say "Super!"
I've a young friend who was OBSESSED with super heros for a few years and while many of us are relieved that he's moved on, it would've been cool to do this for him when he was still into them. I'm bookmarking this for the next opportunity. I know a certain soon-to-be-3-year-old girl who might could use some kind of reversible glamor cape!
