i completely understand what u mean about skinny jeans. i have such trouble finding a pair thats actually cute & my style. instead i wear bootcut & straight leg jeans that are exactly my size or even a size down so they look more formfitting/more like skinny jeans. i also really recommend thrifting jeans if that's an option because i feel like vintage jeans are a lotttt more formfitting and comfortable. also, aside from investing in neon colored jeans, try looking for plaid shorts!!! ive seen them in some scene outfits, and i actually just recently got a pair from my local thrift!
a lot of "basics" can be completely transformed into a scene/emo style if u dont have an extensive wardrobe. flannels are used a lot in different alternative scenes, but you could totally style it in a scenemo way, at least ive seen a lot of people on pinterest do it + i personally have myself. for the scene aesthetic, id recommend going for brighter flannels, like pinks, purples, blues/teals, and oranges instead of more grunge-y colors like brown and green. for more of the emo style, i'd do a basic red/black or a white/black flannel. but that's a little more yeemo than og emo id say.
if u wanna dress a little more fem, id say to look into bolero tops. u can diy your own from an old t-shirt, but i also just like to tie up some oversized button ups. i feel like they add a lot more accessory to an outfit, especially if ur relying on basics for the time being
maybe dont take my word for this because im not actually emo im just Me but there is a Wolf in My Brain who likes to give fashion advice. Yeah
