Anyone ever gotten an exchange through vine?

I just had a nice leather jacket delivered today from a well known luxury brand, and I was pretty excited about it, however the sizing is all wrong on it, to the point that an XL fits more like a large. I can't even raise my arms while wearing it.

There was no size chart, and no measurements beyond the length of the jacket. I would absolutely love to wear it, and hate to just trash it or give it away with how nice it is.

There is no way to contact the seller since it's sold/shipped by Amazon, and I know you are not supposed to contact the seller outside of Amazon or tell them it was a Vine order.

Has anyone had any similar situations where they were able to exchange the item?
