These Jag jeans really do solve the "muffin top" dilemma. And with no belt loops or zipper, they are totally smooth beneath a sweater or fitted top. As others have stated, they would look like "Mom Jeans" if you planned to tuck your shirt/top in, but they are perfect for "un-tucked" tops that skim the waist or are longer. The material is stretchy but also substantial weight so gives good support in the tummy area. For me, they do run a bit long. I wear a size 8--am 5'6" with average-length legs--and even after being washed and tumbled dry, the inseam measures about 33-1/4 inches. That said, Jag jeans have always run a bit long for me. But overall, I'm really happy with the design of these jeans and hope more jean manufacturers follow suit.
