At 5'7-1/2, 128 lbs, I have long legs, so need at least 32-1/2" to 33" length.  Was looking for a higher waist, casual, slim fit jean that didn't break the bank.  These deep black Lee Women's Classic Fit jeans color Onyx that I got in a 6 Long are perfect.  Note, they are not relaxed fit jeans.  They are ample material, 74% cotton, 25% polyester, and 1% spandex, but they are a nice slim fit very flattering jean.  The Longs are about an inch too long for me actually.  No problem though as I have shoes of varying heel heights that will work until I wash these new jeans a few times and hopefully they will shrink up about an inch so that I can start wearing them with my atheletic shoes too.  Love them!
