All original and in perfect condition.  Beautiful glitter and fur dress and authentic stand that says Winters Reflection Barbie no shoes or box.  She has the rubbery legs with the joint pop so maybe 1980’s-1990’s.  That might be consistent with her chunky earrings and blue eyeshadow.
I actually don’t like how they build Barbie’s body these days, I think this version is better but I also could just be nostalgic and partial to this era as I played with these versions.  Pretty for display or play up to you.
