what colour

[Dirk95]

Hi all,
Just something to think about, what if you have been invited to a black tie function would you wear a silk coloured bow tie that would complement a colour in the kilt or hoses. I myself normally wear a black self tie bow tie, why I ask is I've seen it in the past that some wear coloured ties, not quite sure about it.

I would wear a black bow tie.

[Jock Scot]

I second the black tie vote.

[Father Bill]

Black.

[CelticSire]

Black, hence the name "black tie event"

[Karl R]

For an actual black tie, I'd wear a black tie.

If the invitation specified "black tie optional," I'd be tempted to wear a mandarin collar shirt (with no tie, of course). But I'd also want to run the look by a couple fashion-forward friends to make sure it holds together under their scrutiny.

I would totally agree with everyone that if it states black tie then black tie it should be, but as I said I have seen coloured ties I have even seen one guy come to a captain's night on a cruise in black jeans and short sleeved check shirt but had a black bow tie, it did state black tie I supposed he was right lol.

I don't think I've been to a "black tie" event in my whole life, or if those even really exist out here in Southern California!

But if invited to a "black tie" event I'd wear the titular accessory.

I think of a coloured bow tie as being informal, say with tweed

'Black Tie' is actually form or standard of dress (rather than just the colour of the tie). That said, it is only a modern (or novelty) take to add patterned/coloured ties. By 'The Book' (Debrett's) the tie is always Black. The 'standard' is:

Jacket. A black wool (barathea) or ultrafine herringbone dinner jacket, single-breasted or double-breasted with no vents, silk peaked lapels (or a shawl collar - a timeless classic IMO, and never out of fashion) and covered buttons. White dinner jackets were traditionally worn in hot climates but not usually in Britain, even in the summer.
Trousers are black with a natural taper, and a single row of braid down each outside leg.
Shirt. A white evening shirt, with a marcella collar, bib and double cuffs, with a turn-down collar (not a wing-collar), worn with cufflinks and studs. A plain silk shirt with buttons may be worn but any kind of ruffles or frills should be avoided. Alternatively, a fly-fronted shirt, where the buttons are concealed, is acceptable. Adults should avoid novelty shirts and ties.
Studs may be black or decorative.
Tie A black hand-tied bow tie (avoid ones which are pre-tied). The size of the bow tie should be proportionate to the size of the wearer.
Shoes Black highly polished or patent lace-up shoes and black silk socks.
Cummerbunds are not considered essential but may be worn. A matching tie and cummerbund in a non-conventional shade (pastels rather than burgundy and black) should be treated with caution.
Waistcoats may be worn although they are not seen very often. They would always be considered a smart option. A waistcoat and cummerbund are never worn together.
Pocket Square A white handkerchief in the left breast pocket is a classic detail.

Variations on Black Tie
In the country for dinner parties with neighbours, and especially in his own home, a man may wear a velvet smoking jacket, usually navy blue, burgundy or dark green, with a black bow tie, dinner jacket trousers and evening slippers. While this dress is acceptable for the host, it would not be right for a guest to wear this for an event with the dress code black tie actually stated on an invitation, which effectively means a dinner jacket.
Evening slippers, sometimes monogrammed or crested, may be worn and are more often found in the country.

Unless national costume is specified the usual form would be ‘when in Rome’ but in practice smart equivalent dress from a person’s home country – for example Highland, an Indian Nehru jacket or Arabian robes – may be acceptable (as an aside, I love that Debrett's specifically state that hose is 'never plain cream'!)

Hope that assists.
