Argyle/Argyll tweed Jacket and Waistcoat Advice

[xman]

And by the way, is there a reason why some are called Argyle and not Argyll? Surely its just Argyll?

For the same reason that sometimes it's McDonald and not MacDonald. Until fairly recently standard spelling, especially concerning names was simply not the way it was done. Shakespeare never signed his name the same way twice. Even his contemporary Christopher Marlow preferred Marley and never actually signed his name Marlow.
