It is sized very large. I am a 40"-41" hip so admittedly I'm right between a medium and large according to the size chart. I opted for the large and the extra fabric is plentiful, it gathers at the waistband around the entire circumference of my waist and looks like a big tent. This company is one where the return shipping is on the customer so I suppose I will just keep it and maybe it will come in useful at some point. Also, I completely admit that it does say "jersey knit" in the description, I wish I'd read it twice. Knit is the sort of cotton material that is soft and stretchy like a teeshirt. So if you were to wear this underneath another cotton garment the two may grab onto each other and cause the skirt or the slip itself to constantly hike up. It is soft and comfortable against the skin, but it does not behave like a standard slip/undergarment under a skirt. Although far less comfy and not a natural fabric like this one, a nylon slip or a finely woven cotton slip will actually "slip" off of the overlying garment, allowing it to hang freely while a person moves and walks around. It is common sense, this is why a true slip is made of nylon/polyester. And that was what I was looking for. I will keep looking. I can imagine hanging out in the backyard in this, or maybe using it as a pool cover up.
