style issues

Like I'm at a standstill because I don't know if I should be going for early 90's grunge style and build my closet like that, or more for late 90's early 00's skater adjacent aesthetic (flannels vs long sleeve over t shirts, etc.) Pants aren't an issue cause I have pants that can fit both styles, but its mainly hats and t-shirts I'm stuck on, I'm still in high school so I don't have a crazy amount of freedom clothes wise. if I budget myself do a lot of thrifting I MIGHT (big maybe there) be able to go for both to switch between at leisure depending on what I'm doing that day.
