I was looking for a seamless slip that would provide some slight smoothing. I was not looking for any sort of tummy control. This was a thin, light material that did smooth things nicely, EXCEPT for the reason why I returned it: the hem on the thighs was so thick that it showed up through the dress. I was wearing a pencil dress, and when I walked the hem showed. This would be fine with a dress with a thicker material or more of an A-line hem, but not a thin material on a pencil skirt/dress.
