I'd definitely pay more for stuff if it was decent quality and decent size.
I don't know if this goes for worldwide, but the Love Police t-shirts I've bought on tour here in Australia have been getting progressively worse and worse in quality, and the sizes are both inaccurate and inadequate.
I always buy the largest size available, but due to my height and build it usually looks like a skin-tight mid-riff top. Not my kind of look.
When you start making bootlegs, make them in my size and let me know!
