I Need To Know So Much!

I am having a quinceanera in 9 months. I want to start sending out letters to all of y court. I need to know how much money a tuxedo would usually cost in new jersey. My parents think we have plenty of time to send the letters out. I dont want to pay for all of the dresses and tuxedos. We do not have a lot of money so i am not sure whether to have them pay for 50% or 75% of thei clothes. Ll of the people that i chose to be part of my court are not the most responsable people. I want to send out the letters now so that i could have back ups ready. Please anyone tell me what to do. You can e mail me at boricuabyotch659@aim.com or just messege on the site. Thank u sooo much!!!
