Royal Scots Officer’s Balmoral Bonnet 1953

The Balmoral (more fully the Balmoral bonnet in Scottish English or Balmoral cap otherwise, and formerly called the Kilmarnock bonnet) is a traditional Scottish hat that can be worn as part of formal or informal Highland dress. Developed from the earlier blue bonnet, dating to at least the 16th century, it takes the form of a knitted, soft wool cap with a flat crown. It is named after Balmoral Castle, a royal residence in Scotland. It is an alternative to the similar and related (informal) Tam o' Shanter cap and the (formal or informal) Glengarry bonnet.
