Ideas for a halloween costume?

ok so i know it's early to be thinking about a holiday in october but last year i waited until like the week before halloween to make my costume so this year i want to figure out what to be early so i will know i have the costume in time. so this year i want to be maybe something dead or creepy? i also want it to be really unique and different that not many people think to be like one year i was a zombie girl scout and everyone loved it cuz theyve never seen it before. i want it to be something like that! so if you have any ideas let me know i was also thinking maybe dead prom queen or dead beauty pageant contestant but is that pretty common? anyway thanks for your help!
