Maybe it ' s a shout out to how after Bart became Kid Flash in the comics , everyone kept drawing him to look more like a teen Wally than like himself , lol . he did get taller after becoming kidflash in the comics because he had genuinely aged a few years in a day via speedforce but he also inexplicably became a ginger via artistic error multiple times . Idk . Could be that the cut of the costume naturally makes his body look a little different fashion can do that . Could be something else . <| sep |> There ' s my risky click for the day . <| sep |> seeing my gf later tonight , perfect timing <| sep |> No . On the ' dark hat ' there is a brown leather strap with a bucklething on the left side that does NOT exist on the hat we see william select his first visit . In his ' darker hat ' he ' s also an uncompassionate prick to the dying soldier kid . We ' re watching multiple timelines of him and dolores retracing their steps , each time he gets a little more jaded until he becomes the MiB .
