Just AMAZING vintage coatdress!

I bought this in 1989 and I have always LOVED it but I haven't actually when it in 20 years. It has 'sharkfin' design feature down the sides from the waist down and a bright orange lining. It doesn't button on me anymore but when it did I was a size 2. I'd say it's a 4 and if my belly wasn't a little fat it would still button. I'm sad to let it go but carrying it on another move when I'm never going to wear it again is just silly. No rips. an area of staining is shown in images. Might come out.
