In 1798 the Grand Master of the Swedish Order of Freemasons, Duke Karl, decided to design a masonic uniform. The Swedish Order of Freemasons was organised by Duke Karl into an integrated ten-degree system divided in three segments: brethren of St John (I-III), brethren of St Andrew (IV-VI) and Knight Templars (VII-X).
Only brethren of the eight degree were allowed to wear the uniform. It consisted of a blue tailcoat with red facings piped in white, a white vest, yellow breeches and riding boots. The buttons were decorated with the cross of St George.
The buttons belonged to ex-king Gustav IV Adolf in his exile.
