I saw an ad for a custom denim site a few threads down. I gave it a try and the site does have a lot of parameters to customize the fit.

The one complaint I have is that it does not ask for a number for the rise. Instead, there is a waist measurement (around the belly button) and a type of rise (low, mid, high) that you choose. Seems rather counter-intuitive given the wide variation in body shapes.

Has anybody tried it? Any idea about the cost? ( I was too lazy to register). Here is the link: http://www.indidenim.com
