Yes, this is the slimming underwear you have seen on TV! If you haven't seen the infomercial, you can watch it at this website: http://thane.com/products/health-beauty/slimlift_supreme/slimliftsupreme.php
Just so you know - this product does work, but not like they promise. I bought this because I have a wedding to attend and I still look 5 mos pregnant even though I gave birth over a year ago. I've never had problems losing weight until now. I'm dieting and exercising and the baby bulge won't go away. So, I desperately turned to this product hoping that it really would make me look smaller and smooth out my tummy.
The website promises that you can look 1, 2, or even 3 sizes smaller. That's not true. It does smooth things out a bit and makes my clothing feel loose. I might have been able to fit into 1 size smaller but deffinitely not 3. And if you have a larger tummy or larger bulges it won't completely flatten them out. However, it does shape from the bust line to the knee and it doesn't roll up or down either. It's also fairly comfortable if you can get it on properly without hurting yourself. I was unable to get it on right the first time (20 times trickier than panty hose!) and whenever I took a step with my right leg part of the opening that's between the legs (which is for using the bathroom easily, as it's difficult to pull the garment down and back up several times) cut into my leg - it was painful and annoying. Still, even with the leg thing, it's more comfortable than a lot of under garments I've worn. Not as restrictive as most shapewear either. The straps that you can attach are pretty useless though. The fabric is somewhat cheap and flimsy. I don't think it would hold up very long - especially with all the pulling and tugging you have to do to get it on!
All in all, this is an ok product. Comparable to tradtional shapewear garments with a slightly higher price. I would suggest buying it as new on ebay for cheaper if possible. Don't pay full price. Also - you may need to order a size or 2 larger than what you wear. It fits small. However, I would suggest going to a brand such as Spanx - they're in a the same price range but they work a lot better. This really just isn't worth the hassel.
