u/living_in_my_closet

so im lowkey a beginner at sewing, and the project i want to make is quite ambitious to put it mildly, but i have absolute confidance in my own audacity and perseverance. i feel like i could draft a pattern myself but i really dont know what kind of fabrics would fit these kinds of garments. above is a few drawings my friends have done of the character in the outfit i wish to attempt to replicate. the part that im most concerned about is the undershirt, but i might just upcycle a shirt i already have and dont wear anymore for that. any help is appreciated.
