I've worn the Perfectly Slimming 512s before, and was hoping these would come close. Nope. No can do. I'm 5'6", wore size 12 in the 512s, so I ordered these Slimming Bootcut jeans in a 32x32. Compared to the 512s, the rise is WAY LOWER. These jeans are 89% cotton/9% polyester/2% elastin. The denim feels strong although a bit on the thin side. I can't even get these jeans up over my belly! Curvy girls beware, you're not going to get that button anywhere near secure. I sure didn't, I'm apple-shaped. They advertise the "perfect rise" but these are so low that you're trying to button them about 3 inches below your bellybutton. I was expecting the waist to come UP to my bellybutton. Or at least wave hello. Or maybe even be in the ballpark? Two stars for decent, durable denim. These jeans were indeed slimmer through the thigh. My old 512s would flap at the outside of my thighs, way too big. I might get a size (or TWO) up, but on second thought, I just can't stand the low rise. The zipper is too short. These are going back. I'll try my INCs from Macy's. Not perfect, but closer than this. Unless you have a flat stomach, these aren't for you. Or me.
