Very pleased that are are happy with your skirt, I don't want to be a doom monger though in telling you that Robert Burns wouldn't have worn a kilt, and very, very unlikely to have had a tartan, in fact the Burns check is dated around 1959, so relaly very modern
have a look here for more details about it http://www.tartanregister.gov.uk/tar...s.aspx?ref=449
Of course the tartan is very recognizable and always brings to mind the poet, I even used the tartan in covering a protective box for a book.
