I find that clothes shopping is much improved when you can find a good catalog or online vendor and stick with it.
My three favorites are QVC, LL Bean, and US Cavalry.
QVC is a great solution for the jeans issue.
Denim and Company Jeans are comfortable, fit well, and come in more traditional cuts and a variety of styles. They also have a "
custom fit" option. I haven't tried these because the regular 5-pocket comfort stretch jeans fit me just right, and I am a hard-to-fit size.
