Congrats hun <3 It looks like you will be having a lot of fun in the future :)
Congrats! That sounds really cool. I hope you post photos of your costume once its all done!
My husband is a member. Enjoy! He has about 4-5 armored 501st approved costumes. He really enjoys the charity aspect of the group. I know he would say, spend the money and the time to get the correct costume as it will have to be approved by your 501st group. Take your time. It is a wonderful organization. Don't be afraid to ask them for help. Here they have armor parties from time to time to help members build their armor. There is good armor and bad armor so ask lots of questions. My husband has built all of his on his own, but when he first started they helped him a lot with it. :)
