What are some idea's for my 14th birthday party?

Okay my birthday isnt untill october, But i like to think ahead. I will be turning 14. I know I am going to have a sleepover but before that what should I do, as in activity wise? I was thinking hang out at the mall before? im going to have a bunch of people but like only around 5 people stay over to sleepover. Maybe like an ice cream bar. I have done a spa theme for 2 years...do you have any idea's for a chilly october night? I was thinking bon fire? But its an alll girls party for sure. My fav colors are orange, and pink if that helps an dim not very rich so it can't be ike a my super sweet 16 type thing at all. And i need like idea's to do that everyone can do beofore the sleepover with a few people. Like truth or dare, movie is going to happen after the other people leave. I was also thinkning a murder mystrty thing? like there a mystery and everyone gets clues and dresses up? Remember its a cold chilly night in october. I was also thinking man hunt? October 6 is my b-day. Thanks!!
