Thanks all for helpful and robust criticism.

Steering a middle course between North American and UK English is proving to be a mite complex. Where possible I have tried to eliminate words with culturally-specific meanings and use descriptive terms – especially for shirts! I am loath to have two versions of the text for people on different sides of the pond. The second middle course is between the idealistic and the pragmatic: 'what aught to be' and 'what is'. I am aware from my limited experience in the US (helpfully confirmed by Brian K), tuxedos are regularly worn for weddings. For North American kilt wearers, Jock, it seams reasonable to encourage highland evening dress for weddings that take place in the evening (and by implication discourage PC wearing at inappropriate times). On wing collars and cravats – these are now ubiquitous – even in Scotland. Not my taste in collars even for black tie in the evening but not, in my view, a complete no no. Silver ties are common at well-dressed weddings along the central belt, especially among the wedding party (and, I think, preferable to the matching identikit 'rushes' , many in lurid colours, that have recently appeared in Scotland) but I haven't been to a real highland wedding for some 30 years. However, I have attempted to relegate all this stuff to descriptive text rather than implying it is some kind of recommendation. Dress styles, like all material culture, evolve. History will doubtless consign some of these evolutions (especially the ones we don't like) to oblivion while others (like the fold-down jacket collars that have become lapels) will pass the test of time. On thescot's black or brown brogues for day-wear point, I left it open intentionally as, if memory serves me well, even in the highlands (where I lived for a decade and regularly work) both colours are worn indiscriminately, sometimes m@ching but often not.

Any final suggestions for alternative wording welcome before I send this to the webmaster on Monday.

A gent's highland wedding outfit consists of the following -
For a day-time wedding: kilt (usually made from eight yards of tartan wool) with kilt pin, tweed Argyll (or similar Crail or Braemar) jacket with antler buttons and matching five-button waistcoat or kilt belt in brown or black leather (but don’t wear a belt with a waistcoat), brown or black leather sporran and brogues, kilt hose and garter flashes to complement (or at least not clash with) the colours in the kilt and jacket (avoid hire-shop white hose unless you are a piper!), turn-down collar shirt (usually white) and tie (not tartan and often silver or a solid colour).

For a day-time wedding with a more formal look (where Anglo-Saxons would wear morning dress): kilt with kilt pin, black Argyll jacket with silver buttons and matching five-button waistcoat or black leather kilt belt with silver buckle plate (but, again, don’t wear a belt and a waistcoat together), black brogues, sporran with fur front or silver cantle, kilt hose and garter flashes to compliment (or at least not clash with) the colours in the kilt or jacket (again, avoid hire-shop white hose) plain white turn-down collar day-wear shirt and tie (often silver or a solid colour but never tartan). You will also see wing collar shirts and cravats (often silver or cream) worn.

For an evening wedding or wedding reception (where Anglo-Saxons would wear a dinner suite or tuxedo): kilt with kilt pin, Prince Charlie jacket (usually black) with silver buttons and three button waistcoat to match the jacket or the tartan of the kilt (or one of the highland doublets such as the Regulation, Kenmore, Sheriffmuir or Montrose – the last three generally worn with a lace jabot or highland cravat) , full dress sporran with fur front and silver cantle, kilt hose and garter flashes to compliment the colours in the kilt and jacket, or tartan or diced hose that match the kilt, black brogues or buckle brogues, white wing-collar or turn-down collar evening shirt (tuxedo shirt) and black bow tie. Following day-time weddings, it is normal for kilted grooms and guests to go on to evening receptions in the day wear or morning dress that they wore for the wedding itself.

Although rarely worn in Scotland any more, formal evening dress could include a plaid (fly plaid or belted half-plaid), which passes under the epaulette on the left shoulder and is secured to the jacket or doublet by a large plaid brooch. Dirks are rarely worn and are inappropriate for a church wedding (where weapons should not be carried). However, a sgian dubh (or a safety one without a blade) is often worn in the top of the hose (more a utility knife than a real weapon but make sure it is legal in the country or state where you will be married!). A couple of things to avoid are kilts that are too low and hose that are too high. If they meet, you’ve got it wrong! The top of the kilt should be at or slightly above your belly button and the bottom at or slightly above the middle of your knees. Hose should be a couple of inches below where your knee bends. Apart from laws about carrying of knives, there are no rules about Scottish highland dress but there are traditions and conventions. These should not dictate what you wear or prevent you from being creative and a wee bit different but knowing the form should help you look your best on your wedding day.
