First off, these jeans might say they are "black forest", but they are NOT black (nor the color of a forest at any time!)and the picture makes them appear much darker than they are. They are dark blue denim; definitely not black. As for size, I am 5'7", 128 lbs., and ordered my usual size 8. The jeans have some stretch to them, so after wearing them awhile, I felt they were a little baggier than I like. I think I should have ordered a size 6. I definitely don't think they are worth what I paid for them as I can get Levi's at Walmart for half the price that are made from the exact same-weight denim and look just as good.
