I already purchased the burgundy set last year before it sold out the pants were a medium when I got them . I wear a size 11 in FN jeans they were too loose for my liking . so when I got these 2 other colors I got a small in the bottom and top they fit perfect but still give you that sweats loose fit , hands down my absolute favorite I need every color I’m buying them all and such great quality and keep you warm . the length is long they drag on the ground I’m 5’4 but it doesn’t bother me I love long pants .
