I get mine from Lands' End because they do free hemming. They have a variety of fits - some good for apple shapes, some good for pear shapes.
However, if you have small hips, there were only a few styles that came in size 00P last year, and these are now backordered until April. And it looks like only one style of the chinos in Junior's sizes has size 1 in stock currently .
