I am 5'4", 145lb, 28" waist, not apple or pear shaped (fat distributed kind of evenly).  The petite 6 regular (29" inseam) fits me like a glove, just a tiny bit loose around the waist band.  I haven't washed the jean yet therefore I don't know if it'd shrink (according to a few Zappos reviewers, it won't).  The pressed black is a very dense black.  Again, a few zappos reviewers said that the color did not fade after washing.

29" inseam is a good length for wearing flats or heels less than an inch.  I wish it'd come in 30" inseam so that I can wear shoes with a bit of heel.

Overall, I am pretty happy with this jean.  It looks good enough to wear to work.

Update 5-31-2011
I lost 30lb since December 2010 therefore these jeans no longer fit me.  The petite size 0 is perfect for me now (5'4" 115lb 25" waist).
