I posted the following in another thread, for fear of a highjacking, have decided to take it to it's own thread, so what do you say regarding the formality of different day wear kilt jackets? To me and many others there is no difference in formality as these jackets are essentially the same, the only difference being the sleeve detail. The descriptions below were copied from Scotweb.

Argyll Jackets
The Argyll day/evening jacket is versatile, altering its formality with accessories.
Suitable for all occasions, from dinners and Burns Suppers, balls and ceilidhs, to weddings, graduations,
Highland games or simply as general day wear. The brown Argyll I'm wearing here is definitely day wear, though the style could work at more formal occasions depending on the material used.



Braemar Jackets
Similar to the Argyll jacket, but with more formal Prince Charlie style cuffs,
the versatile Braemar can alter its formality by changing accessories.
Suitable for all occasions, from dinners and dances, to graduations and weddings,
or simply as smart day wear.


Crail Jackets
Similar to the Argyll jacket, but with less formal plain cuffs, the day/evening wear Crail outfit
is often seen at events such as ceilidhs, games, or simply as general office or day wear.
Also suitable for wedding guests too.


I hope this helps.
