Yup. Scale and chainmail mixed with faux leather armor and lots of coverage. Because face it, chainmail bikinis may be fun to look at, but they're ridiculously impractical.
Pish. I'm not actually gonna be that encumbered, I don't think. The mail is all aluminum, and the vinyl faux leather is going to be backed by craft foam. It shouldn't be that heavy, and I'll just tell people it's magical armor.
Besides, Jean should rightly be a psionicist, not a mage anyway.
