Its for school. would this be proper 80's metal clothing?

Youve got a good start going there, but I recommend a more colorful sleeveless shirt. The eighties was about bold, bright colors, so if you're gonna go with black skinnies make sure you have a brightly colored shirt and shoes if possible. The camo converse may get you by, but if youve got any checkered vans or any colorful shoes you gotta wear those. And do your hair big too. The eighties was big, bold, and bright. Have fun with it :D
