Urban Street-Wear Culture

I have an event coming soon and our teacher told us to wear vintage hip hop clothing but I have no clue what that looks like! i looked it up on google but I highly doubt those ruffled dresses is the style my teachers going for..
is vintage hip hop the style in the chris brown’s music video "gimme that" ?
where could I get these outfits and what vintage hip hop outfit would you think of for a girl?

here are a few ideas:

also, look at a couple 80’s hip hop artists.
like when hip hop was just starting.

hope i helped!
have fun and good luck!
