I was at a jeans boutique yesterday and they were selling fleece-lined tights by a company called Plush. I was really intrigued, especially because it was frigid here yesterday! Has anyone tried fleece-lined tights? If so, can you let me know if they are bulky, and if they sit up or end up rolling down at the waistband (I hate tights that do that!). These were $40 a package, so I would love some feedback before spending that kind of cash on tights.
