it is concealed or covered up? Or does MT mean that the jeans don't fit? In other words, is it unavoidable in certain circumstances?

I've only recently had an issue with muffin top, and I feel very uncomfortable about it. At the same time, for certain of my jeans to stay on, they have to be tight enough that there is a bit of pinching (without discomfort). I just hate the way it looks and feels, even if no one else can see it.
