Misses vintage Mothercare Maternity Pinetta Size M; 65% polyester, 30% wool and 5% OF (assumed other fibers); these pants have a black elastic strip as shown with 7 button holes in it for adjustment. There are also two buttons on each side to adjust the front; I did not measure the waist since it has so much adjustment; These are cuffed and to me feel like a lightweight twill; I know the pattern looks like modern day pajama pants but I "think" they are meant as vintage red/black dress pants, especially with the cuffs and 30% wool content. They are in good shape. There are two deep side pockets.
