The lining of these custom skirts is made from our Silk Sensation fabric which is lightweight and smooth with a satin face. It has a lovely drape and feel, and is stitched so that the satin face is the side against your skin so that it is cool and soft to the touch.
You can't, the skirts have a drawstring detail, so it doesn't go all the way around the elasticated waist band, only across the front two centimeters. The drawstring is approximately 11.02", from the exit in the belt to the end of the toggle (which is 5.9" long with a 0.2" diameter at the bottom) which is slightly tapered at the top, and is silver in color.
Yes, the lining is the same size across all three skirts. This is not just for comfort. The fabric of the skirts are extremely lightweight, and especially with the MulMul Soft Muslin, has some transparency. The underskirt lining not only incredibly soft, giving a luxury feel to your skirt, but also acts as a modesty panel; especially if your skirt design uses very light colors and you have darker underwear on.
