This vest is a great layering piece for fall and winter as it can be layer on top of a button down and worn open, over a turtle neck, or a sweater. It is a medium to heavy weight material and has adjustable straps on either side for cinching in the waist if desired. It also has functional pocket and is lined. *There Is a slight blackish under one of the front buttons. And the collar could be cleaned up a little, but thank goodness for the washable suede! See photographs for measurement and material information. Happy to answer any additional questions upon request!
