I love this vest! It is super warm and super stylish! I actually can’t get over how warm it is considering there are no sleeves. The vest is oversized in shape which is current and on trend. The side slits make for great design and ease of movement when the vest is closed. The side slits can be worn open or closed. It does run a bit big so if in between sizes, I would size down. I went with my normal size and have a bit of extra room.
