concert fit

hi guys so i'm going to see ptv on dec 5th and i still haven't rlly settled on an outfit... its in 9 days. LOL. uhhhhhh.... so, i was thinking a purple cwts shirt (i got it from hot topic) with a purple undershirt and maybe a studded belt if i have time to go buy one.. OR my red roses ptv shirt with a red undershirt and black and red studded belt that i already have. i think i might try to wear shorts to this just incase it gets hot.. but maybe if i wear shorts i can put red/purple leggings under which would be cute. lmk guys
