my tip is ACCESSORIES ARE YOUR BEST FRIEND! you could have a simple colorful outfit maybe some skinny jeans, a tutu, a band shirt, denim shortz, or anything invader zim are som options but once you add accessories it makes it much more like the scene aesthetic. Some accessories are colorful or striped armwarmers or socks, colorful tights or fishnets, kandi bracelets or rubber bracelets, hats like baseball caps with scene designs or characters like zim, domo, mlp, etc// Also lots of scene kidz wear belts! Studded belts to be exact, they could just be black, silver, or colorfull and most scene kidz dont wear them in belt loops or wear them layered! Thats just a few things but I recomend researching some more accessories aswell if you want (sorry if my spelling is terrible)
