Big white tee's, Baggy pants/sweats. Basically dressing like Nelly. Always big basketball jerseys with the authentic 2000's design if you can find one. Good luck on the drip.
the shag. pretty much my classmates had that hairstyle back in middle school spmetime around 2009-2011. like what justin bieber or shane dawson had back in 2009
hip hop was super prevalent in a lot of "2000s" fashion and one of my favorite trends from then would probably be the solid color tees (3-5xl each don't be forgetting)
