I have a pair of the demi curve in boot cut in a size 12 regular, they fit ok, but they are short on me.  I got these hoping they would be long enough, I am 5 '7, they are not, and they are also tighter than the boot cut demi's were.  I do wear a 12 in Levis 525's and 529's and they fit fine.  I was really hoping these would fit.  I have an hourglass shape, and got measured at the Levis store, and was told the demi curve is what I should wear.  Maybe next time.
