about it this morning. There's these jeans out. They say can help shrink your waistline. Abb abbie boudreau has the latest on this fashion. Reporter: They're the style that keeps coming back. Skinny jeans. The perfect pair, a must-have in so many women's closet. Show off those legs. Show off your assets. Reporter: Now, new denim technology promises to shape, nip, tuck and limit. A lot of the jeans say you look one size smaller. Do you have room to kill? To go down from an 8 to a 6 or a 12 to a 10, it's a miracle. Reporter: A miracle, maybe. But build-in invisible stretch panels that help smooth out your midsection. No more muffin top. Reporter: J. Brand lady denim, sold at stars like bloomingdale's, which uses a slimming, stretch technology. Then, levi's rebels, a body-shaping jean, that says it will make you look slimmer. Using liquid technology into the denim, to help the jeans hold their shape. Do they really work? We asked shanna, tammy and jewels to give us the skinny on the new skinny jeans. Looks like a lot of support, which is really good. It feels skinny. It feels like spanx, like in den denim. Reporter: What makes this work on her? Before she was wearing these wide-legs. Just hiding her body. The way it's contouring her body, it shows off her thighs. Look superskinny in these. I love it. Tami, turn around. I love it. Your butt is on a new plateau. It's amazing. Reporter: A higher waistline eliminates that dreaded muffin top. Slimming stitching and higher pocket placement give that extra lift. And the liquid technology promises to hold it all in place. Still a skeptic, I slip into a pair to see for myself. They kind of do give you a little bit of a lift. For "good morning abbie, for that report.
