OK so this weekend we're off to a ceilidh and rather than wear my jeans I've decided to wear a kilt. Two questions:

1. Is a girl's kilt a kilt? Officially, I mean? Or is it just a tartan skirt?
2. According to my man (this is the bit I'm thinking he's kidding) I should join him in wearing it 'traditionally' (ahem). He's kidding, right? I'm not Scottish! And it's a guy thing... surely??
