As Brian is in the Army, the Royal Regiment of Scotland, he wore his dress uniform for the wedding. His best man also is also in the Army, so he wore the same kilt as Brian in order to match.
Brian’s uniform was Scottish Infantry Number One Dress, and his kilt was Cameron of Erracht tartan, which is a heavy-duty kilt. He wore his medals for his operational tours of duty of Northern Ireland, Bosnia, Iraq and Afghanistan.
The piper at the ceremony was a close friend of Brian’s and also served in the same regiment, so he was able to wear the same uniform to match the groom and his best man.
