Late Roman belt

[Medicus matt]

a) dots like these are a well-known technique in art to show a mail shirt. There is no compelling reason to deviate from such an interpretation in this case. In fact, it’s what all the experts think, and I’ve yet to see other interpretations.
b) a dotted tunic would be something new in late Roman tunic fashion. Talk about a lone piece of evidence – or can you come up with more dotted tunics?

a)It's brown and looks like it's made from fabric. Are other examples of this technique of depicting mail also brown and fabricy (if that's not a word then it is now)?
b)I've never seen a 4th century depiction of a 14th Century BC egyptian soldier, so I don't know what he's attempting to portray. Whatever it is, I (personally) don't think it's a secure representation of a 4th century Roman.

I don't WANT to argue the 'evidence' away, I was quite happy wearing a wide belt over my mail (they're very slimming ). However, for me, the evidence to support the common wearing of these wide belt sets (and lets limit it to that because the wider debate over what is a belt and what is a sword belt when depicting narrow belts worn over mail is much wider), with their associated dangly bits, on the battlefield (over armour or otherwise) isn't there. I'm not going to stop anyone else from doing it; there are bigger horrors out there than that, I'll just save the wearing of mine for when I'm wearing my finely made tunica (something else I wouldn't wear under armour), drinking wine and eating Imperialist tidbits.
