For sale is a pair of J. Crew women's stretch pants in size 2R but I believe a trim size 4 could possibly wear them too.  Lying flat they measure 13 inches across at the waist, 17 at the hips.  The rise is 9 and inseam is 29.  The fabric is stretchy and heavier than you want to wear in the summer.  They are very flattering and could be dressed up.  Casual would be difficult because they have to be dry cleaned.
