Just trying to extract information from the conversations...
Short answer is "yes". Mess jackets usually have the body in one colour (often red in the British army) with the lapels (and sometimes the cuffs) in a different colour, defining the regiment. Waistcoats are often black, although red is by no means uncommon. A few mess jackets fasten at the neck, similar to a Sherrifmuir jacket, and have a "bib" underneath, again in a contrasting colour.

Costello & Son in Ilford, London, supply much of the mess dress to the British forces (including RAF, Royal Marines, Royal Navy, the Royal Household, etc.), and examples can be seen on their website.
