I like the product. Helps trim me down a little under the clothing. The rubber makes you sweat. After a couple days of wearing it, I really do feel trimmer in the middle. The immediate compression isn't as much as my steel boned corsets, but is pretty decent for shapewear. I'd say an inch plus a little more in the areas that need extra smoothing.

However, I don't recommend it for all day (10 hour) wear. I'm so itchy by the time I get home. It is cotten on the inside, but it still itches by the end of the day.

In terms of fit, I am a 20, usually. Sometimes an 18. I bought a 3XL. It fits fine. I am short and it does indeed go from hip to just under the bust.
