These are from the Fall 2012 collection. No fabric tag inside. Feels like a soft wool blend with some stretch. Side zip. See closeup photos for details of fabric design variations. When looking for a fabric tag I saw a light round spot on the INSIDE of the back of the pants, shown in last photo. You can see it is barely noticeable on the seat of the pants in the wide shot, and only noticeable when looking closeup on the outside. Possibly some sort of repair or just a variation in the fabric. Waist measures approximately 15.5” across and while they run a little big and have some stretch, they are NOT high waisted so take that into account with regard to waist size. Front rise from crotch seam is about 9.5”. Really gorgeous pants.
