When being invested one has two options if one chooses to wear Highland attire.

OPTION 1: Court dress, as per the rules set down by the Office of the Lord Chamberlain.

OPTION 2: Morning dress. In this instance it would comprise a black Argyll jacket with matching waistcoat, white shirt with fold-over collar, silver grey silk four-in-hand tie, dress (or best) kilt, silver mounted sporran, diced, tartan, or dark solid coloured hose, black silver-mounted sgian dubh, black shoes.

Morning dress is to be preferred, and all aspiring X Markers would be advised to have all of the above packed and ready to go at a moments notice in the event of an unexpected command to attend on Her Majesty for the purpose of an investiture.
