Nice monochromatic stretch grey top shop pant with grey sweater

Topshop grey stretch 100% cotton pull stretch pant with grey sweater. Pants are form fitting with a lil stretch and so sexy. A lil mark on pant as shown in photo. Sweater is NOT TOPSHOP It is from a small boutique in west village nyc. There is no tag in sweater. It was my favorite. Too small for me. Not sure if fabric. Both go nicely together for fall. Pants are size 8 and sweater is a small. Both as is exactly shown in photos
