The Norse Outfit. The necklace is stitched down so she can't get tangled up in it, and the "brooches" are buttons.
I know a lot of Norse and Heathens and they would all do the *squee* if they saw her (and I'm talking the big burly ones too).
Ha ha, I'm a Heathen myself, and yes, yes they do.

Took her to Pagan Pride Day in Vancouver in her two-year-old version (same think, just scaled up) and it went over very well.
I'd be happy to share details/patterns; it's really very simple to make. Most of the impact is in the nice bright trim and that she's so tiny, ha ha. And then one strap and that side of the apron is stitched together and the other strap attaches to the front part of the apron, and the front piece to the side piece, with hooks and eyes, so it's super easy to get on and off.
Her brother has an outfit too but he's kind of going sour on it. It's a T-tunic, of course, and with his shoulder-length hair and what too many mundanes think is a dress everyone keeps thinking he's a girl when he's wearing it! At least, when he was wearing it at the park the event was at; lots of adults but I don't think (m)any of the kids there were involved.
