This slip is seamless which is exactly what I was looking for. I have a FL&L dress that has a bodysuit attached but it is not quite wedding appropriate so I had to find a slip that would cover where the bodysuit ended. The only issue I have with it is that it clings/folds underneath the dress but I will make it work. I am 5'4 140 and ordered the Small/Medium
The material is soft, and the fit is true to size. My only issue is that it doesn't stay put during my commute to and from work. If you're going up stairs with a backpack or hopping on and off public transportation, it will ride up.
