I’m lucky that I have a pretty average body, so most things fit reasonably well of the rack. Because of that, I buy all of my jeans at consignment stores. That way, I can be a demin snob (seriously, I hate the feeling of cheap demin) without spending more than $50 or so per pair.
The only downside is that I never can seem find good skinny jeans at consignment stores, so my one pair of skinnies came from Old Navy. I really wish I could find a “good” pair of skinny jeans, but I am not about to spend $200 on something that won’t look that much different than my $30 pair.
