DVF Vintage Silk Black & White Jacket open sizing

Selling an excellent condition, vintage silk Diane von Furstenberg jacket. The jacket is unique, with a cream grey silk overlayed with a black crosshatch silk pattern and a snap button lapel. I love the style and feel of the jacket but it is too big for me. I’m a size 2 and the jacket is a little too oversized on me and would look great on someone taller than me too! I bought the jacket at a vintage store and the material and size labels are missing. The jacket is a one size, open fit. Length from shoulder to hem is 22inches.
