How did they make those Lady Gaga costumes?

I'll add an update on LIFE in a little bit but for now, I have to discuss Glee. I'm watching season 1 on Netflix and sure, it's cool for what it is, but I'm a realist, so sometimes it's hard to suspend reality and just believe that a teeny high school glee club is suddenly flush enough with funds to have smoke and flames shooting from the stage during a performance of a Kiss song...for exactly 8 audience members. Though, I guess it is a good exercise to jump into loopy-land for a bit and watch a performance of Bad Romance complete with a professional stage and lighting. Certainly, Glee is entertaining, but it doesn't GRAB me like a good drama does. It seems to serve as a vehicle for musical entertainment. Luckily, they sing well. Though, I did enjoy the twist with a main character singing Jesse's Girl when he finds he likes a girl who is dating a guy named Jesse in the group. Nice touch.
