@chai2,
Yeah, Set's logic makes sense, I don't know anything in particular about this... wasn't rebutting him, his post wasn't there yet when I typed (I'm zoomin' around today and doing drive-by postings now and then...)
Inner just seems simpler to me... less
stuff going on on the inside rather than the outside. Plus you didn't say they were too big overall, just that the legs were a bit too wide. It seems like you'd want to keep the leg line straight on the outside, rather than getting a taper effect (curving inwards after the hip).
So that made me think that doing it on the inside would temper the leg fullness a bit without messing with the fit around the waist/ butt/ etc., and keeping that straight fall from the hip instead of a weird taper.
I'd have to actually have the pants and mess with 'em to see how it would actually work though.
Have you done anything yet?
