I also want harem pants. I wonder if they're difficult to make. O'course, I don't have a sewing machine :P
I wonder if I could find a bunch of sheer black curtains at some thrift store and make stuff out of that. or get sheer white (which I know they'll have, they always do) and dye 'em. In a nifty tye-dye-ish purple-black-red-blue thing. That might be worth a try.
Of course, if I really want leather I could try cutting up my old leather pants that don't fit and making a harness type thing out of em.
Yet another project that I'll keep thinking about and never actually do - but it's fun at this stage, at least :)
