I have been trying to figure out the sizing on these Levis. I really like the jeans and the pair I ordered in a darker color fit perfect. So I ordered the same jean in the same size but different color. I am tall and thin and for some reason this color fits very tight around the thigh. So I ordered one size bigger in the waist and still they are tight in the thighs. Like I said I am thin and have even been asked if  "I'm riding a chicken" so my thighs are not large at all. Also this color is much thinner denim. I don't have an answer as to why the completely different fit in the same cut and size but it is very frustrating. I guess I am doomed to wear the same color of jeans if I want to wear the 527's

UPDATE: I decided to try these one more time in a different color, "Wave Illusion" and they fit perfect just like they should. They are also the heavier denim that I'm used to with Levis. I have had my share of problems ordering these jeans so now I'm left to wonder...Did I just get lucky this time?
