I pretty much wear jeans 7 days a week, and am considering buying some better quality denim. I'm 5'4" and a lot of the size charts have that on the cusp of being considered petite. The inseams on the petite sizes are listed about where I want them, but I also know they adjust the knee break in petite sizes. I haven't bought anything petite before, so I'm not really sure if I would be petite or not. If I am petite, should I size up? I'm 3 hours from the nearest Nordstrom, so I may be stuck ordering online and returning.
