Origin and Use of "Dress" Tartans

[PEEDYC]

I would find it extremely interesting to know three things: (1) how many "dress tartans" are there; (2) from whence do these date; (3) how many have "official standing" within the clan?

Can someone please enlighten me?

Try this link for a start. It is the Scottish Register of Tartans. It may not help you though if you read the post (49) by MacLowlife re the Campbell tartans. There are Five Campbell (Argyle) tartans registered and Campbell of Loch Awe as well which the Clan Chief does not regognise according to that artice. No wonder people are confused over rights to wear tartans and what is a true tartan.
