In my series, Oops Comic Adventure, I try to use attire change as a way to show character growth. Like both visually and mentally, Oops isn't the same kid from issue 1 that he is in issue 6


(he lost his hat here. It was a big change that the readers definitely took note of lol RIP hat)
I got this idea watching Avatar Last Airbender and how with each season Aang and the gang changed and it also felt like they grew up from season 1 to season 3. Season 3 having the most noticeable change with Aang growing hair and everyone dressed in red fire nation clothes and lots of growing up and preparing for the final show down.
I try to incorporate those things into Oops, as well, because it felt like such a subtle yet noticeable detail in Avatar.
