(I'm a female) I'm going on a bit of a shopping spree, looking to expand my closet. I have a very 80s heavy metal style, with a bit of grunge and punk. I'm also into a bit of 70s glam. What clothes/accessories are a MUST for someone with my style?

Note: I'm a teen and my school has rules about some things we're allowed to wear and not allowed to wear, but I break them all of the time anyway so it doesn't matter.
