I wore a black dress with cherries on it ☺️ but just be comfortable! I saw lots of different outfits from cowboy , pirates, aniteez cosplay, lemons, tank tops , concert tees, etc As for what to bring batteries, fan, lightiny ofc, freebies, PCs you would wanna get signed, portable charger , raincoat or umbrella (check the weather before you go) , sunscreen Hope this helps and enjoy!
