How to get chosen for Taylor Swift t-party? ;) poster? shirts?

Okay, I need your help. Today my mom was acting all suspicious and she kept calling me "swifty", then bam!, she comes home and show me Taylor swift tickets. I was jumping around and screaming, and ya. So, I am 14, my twin sister is too, (both girls) we are going, so is my mom and (maybe) my dad. What should we put on the poster? glowsticks? I know where to get poster lights too, lol. I am wicked excited. or what should i write on the poster? again, we are twins, so if you think of anything that has to do with that we could put on the poster that might help? I was also thinking to make a half heart on my shirt, same on my sisters, the a 1 in her half, and a 3 in my half, so we stand together and it makes a 13 with a heart? I don't know! lol, any info would be helpful, thanks :) anything to write on the poster? Any ideas would be helpful, thank you, thank you! I probably am repeating my self, but i am excited. thanks ! :) have a fabulous day. btw we are going tomorroww, not to brag or anything. sorry. :D sorry if this is in the wrong catagory, i dont know where to put it! thanks ;) Ps, maybe an idea of what to wear? thanks. ;)
