From Jalie website:
"Leggings, stirrup tights and mini-skirt that are great for layering with your favorite tops or cardigan. Leggings and tights have and encased elastic waist. The self-lined mini-skirt (no hemming) has an exposed elastic waist for minimal bulk (since it is designed to be worn underneath longer tops).
RECOMMENDED FABRIC: Knit with 60% across the grain and in the length"
