Part of the particular appeal of the Ball is that everyone attending is wearing traditional formal evening dress. The dress requirements are stated below in summary and in detail.

Please note that those not correctly dressed will be refused entry.

If you are unsure about any aspect of the dress code, please contact the Ball Secretary.

In summary



Ladies


Full length dress



Gentleman


Highland evening dress, or

Evening tails with white tie, or

Mess kit

No dinner jackets


In detail



Ladies - essential


Floor length evening dress, or

Mess dress (for those entitled to wear it) with full length skirt



Ladies – optional (but encouraged)


Tiaras

Clan tartan sashes

Orders and Decorations



Gentlemen - essential


Highland evening dress comprising kilt and sporran, evening jacket of black broadcloth or coloured velvet, white evening shirt and black bow tie or lace jabot, or

Evening dress, comprising black evening tail coat, white shirt with wing collar, white bow tie and white waistcoat, or

Mess dress, worn according to regulations, with, preferably, where permitted, any more formal variation such as stiff shirt, wing collar and black bow tie



Gentlemen – optional


Orders and Decorations


For the set reels gentleman taking part must wear highland evening dress or mess kit, tail coats only if part of mess dress, and ladies must wear clan sashes.
This would tend to corroborate the idea that the jabot is the only white tie equivalent in highland dress (though I have seen white bow tie and waistcoat illustrated with a regulation doublet) and that a black bow tie with highland attire can be substituted for white tie and tails (the converse of the dress code here).
