A year or two ago, I won a collection of Jenny friends on eBay, and never sorted out the extras that I didn't want. It's hard for me to part with any Jenny friend, because almost all of them are hard to come by in the US.
This is a Naomi. I couldn't find any info on her through Japanese sites, but I think the swimsuit is her original fashion. She's probably a shop or event exclusive. I'm not too fond of her face paint color combo. I tossed her on eBay, and still feel kind of regretful. One day I'll find my dream Naomi doll, with a more natural color scheme.
