Junior House Vintage Tailored Jacket-Size 9/10

Junior House Vintage Jacket with three quarter length sleeves. It is authentic vintage and most likely from the 50's. Due to age, it has yellowed a bit. You can either wear it that way or die the jacket. The tag says it is made from Acetate and Cotton and is "dry clean only". Note that the bottom button does to match the others and it looks like it was replaced with a button that was probably clear at the time. This is a vintage product, so it will have natural signs of wear and age-please look at pictures and I would be happy to answer any questions. PS-also look at measurements as I have seen that sizes ran smaller than they do today
