I would want PKW's advice on this but are we sure those eyes (ignoring the eyeliner bleed) haven't been touched up with paint? It's just how that one side it comes in rather suddenly on the iris...
I've seen dolls stripped for custom or repaint but I wouldn't like to guess from a photo if that is one of them or an actual release. All I can say is that I have never seen a Megan that looks like that before.
I have my one in the US dress sitting on the bed with me at the moment (but she was bought here in the UK, she is just wearing the US dress. I think. I can't remember 100% any more >< but I think that's right). In any case, her paint is not the same but she's not from the same release so that doesn't matter in terms of eyeshadow. I just wanted to see whether her eye paint comes in like that on her eye - and it doesn't. It looks a lot smoother and more blue black. I really am now going to go dig out my Megans. Pandora's box is open ><
ETA - four Megans found, checked. (One in US dress but probably from UK, one from UK 1986, one from UK 1987, one from SS Sundance set)
All have eyeshadow.
All have blueblack eyeliner.
Three have curls.
None look evil.
