I am a big fan of Chico's jeans and pants. Their sizes are done differently. A "1" is 8-10, etc. But most of their pants come in 3 shapes, O (original - hourglass), W (woman - bigger in the stomach than hips) and M (modern, low on the hip).
I'm more of an hourglass figure, but since having babies, my stomach is flabby...otherwise I could probably wear one size smaller than I do.
Many Chico's clothes are gawdy, but their jeans and plain knit tops are really good.
