1970's Vintage Trench Coat w/ removable lining

A stunner from the 1970's, from a Brooklyn Vintage Market - this trench coat is warm with a liner that is removable. I got the coat tailored to lay just above the knees (it was down to ankles). Says Size 9, but that would be the 1970s sizes. If you look at the photos for sizing purposes, I am a size 0, 5'2, 115lbs and so I would say it fits size 0-2.
