Kilt Do's and Don'ts

[DWFII]

I don't believe it's a claymore at all. It's a basket hilt sword (just under his elbow) and the scabbard is, indeed, caught up in the kilt.

I think if you look closer you'll see he's wearing a fly plaid. The plaid is hanging over the scabbard. i might be wrong but that's the way I see it.
