So yeah: a whole lotta T-shirts going on. On page 10 alone, he changes white shirts three times between five panels. There is a pair of brown pants that goes with these shirts, but I will post them in the next update. On page 12, Johnny's wearing jeans and a grungy cut-off (it's purple in the comic, but probably meant to be grey). The funniest thing about this shirt is that I struggled through three mediums before I realized I have a Sharpie marker that should be labeled "comic book lavender".
Believe it or not, there's still much more to come from just this one opening comic book! As mentioned before, the costume changes taper off in a big way about 1/3 through the series, but we'll enjoy them while we have 'em!
