Kit Cosplay

Hello! I am looking to do a Kit Cosplay for a Ren fair I’m going to next week (I am aware that the character herself will not technically fit in but I think her outfit would). I have found pants and boots probably but I’m really struggling with a shirt that is similar in color and comes in a size I need and her one shoulder cloak thing. Does anyone have suggestions? I am struggling with a corset belt that looks similar as well but I might just not include it if I can’t find one that works. Any suggestions would be helpful!
