About 10-15 percent of Comic-Con attendees come in costume and they are always willing to post for photos.  I love the way there is total fluidity of age, race, gender, and body type.  Even species — see Superdog below (no, that’s not Krypto — look at the super-suit and arms!).  Everyone feels free to come as whatever they want to be, whether an iconic character or something they just made up.  Here are some of my favorites.
