What black tie actually means in Toronto

The invitation says black tie, and here that instruction meets a coat check before it meets a room. Most of the gala calendar runs through the cold months, so the first thing anybody sees of you is an overcoat and a numbered tag, and the entrance happens forty feet later, once the wool is gone.

Half the room came up an escalator from the concourse under Bay without going outside, half came off the 504 with brine drying on a hem, and all of them read the same card and guessed. The literal meaning has not moved in a century. What Toronto does with it is looser than the card claims and stricter than people hope.

What the card is literally asking for

Black tie means a dinner jacket, a garment and not a synonym for a dark suit. Its lapels are faced in silk or the flatter ribbed grosgrain, cut peak or shawl, and answered by a stripe down the outside seam of the trouser. A notch lapel is a business suit in costume. Under the facing sits barathea or a dull-surfaced worsted, because the design depends on matte wool against shine. Midnight blue exists for a reason: black photographs slightly green under artificial light, and midnight blue reads blacker than black.

There are no belt loops. Trousers hang from side adjusters or braces, never cuffed, with almost no break, one soft dent where the hem meets the shoe. Fabric pooling on the instep is the loudest rental tell in a room. The shirt takes a turndown collar and a marcella bib, that stiff waffle-weave cotton, fastened with studs, and a cummerbund covers the waistband so the dark runs unbroken from shoe to collar. Shoes are patent or black calf polished hard, over knee-length socks. Tie your own bow tie; the slight unevenness is the credential.

The gown side, at the same resolution

Floor length is the literal reading. The honest question is which fabric you want to spend four hours inside. Duchesse satin holds architecture and shows every ripple, flattering a standing silhouette and punishing a seated one. Silk crepe drapes and forgives. Velvet behaves like a second coat, warm enough that a February ballroom reminds you of it by the speeches.

Hem length is calculated standing, in the shoe you will wear. A gown hemmed over a nine-centimetre heel and worn with a flat drags on a floor every salted sole in the room has crossed. Clear the ground by a centimetre.

The flash does predictable things. White metal and diamond pavé blow out to a smear, sequins bounce back hot and hide the shape of the dress, matte crepe and velvet come back as true colour. Coloured stones survive it best, which is why emerald and sapphire keep turning up, and pearls hold when the rest goes to glare. Earrings outwork a necklace, because the step-and-repeat frame crops at the chest. The fine jewellery guide covers who does that work here.

Black tie optional, and the creative variety

Black tie optional means the host wants tuxedos and gowns and will not blink at the alternative. The dinner jackets never take the room. Everyone else goes navy or charcoal, white shirt, dark tie, black shoes, nothing with a pattern in it.

Creative black tie keeps the structure and plays one card: a velvet dinner jacket, a jumpsuit, a woman's tuxedo cut close through the waist in the line Yves Saint Laurent drew in 1966 and never improved on. It turns up on September invitations, when the film crowd is in town, and almost never in February, when the room dresses down the middle. What to wear during the festival takes September further; the wedding guest guide handles the black tie wedding.

The alterations calendar people always get wrong

Six weeks. That is the number to hold, and almost nobody does.

A bench that turns a jacket around in a fortnight in July does not in November, when every dinner jacket in the city arrives at once. A gown needing the bust or waist moved wants two fittings a week apart, sometimes three.

On a dinner jacket you can change sleeve length, waist suppression and hem. Shoulder width is a rebuild. On a gown you can move a hem, take in side seams and reshape a bust, but letting out is capped by the seam allowance, a centimetre or two, which is how a dress bought on the promise of a diet ends up unworn. Reseaming a lined gown costs several times what a hem does, because the lining gets rebuilt with it. Bring the shoes to every fitting, and the real undergarments.

Getting there in February

Salt is the whole problem. It leaves a white tidemark on satin that never lifts, and patent wipes clean with a damp cloth, which is the argument for changing shoes at the venue.

The coat either covers the hem or stops at the high hip and lets the gown carry it. Anything landing a few centimetres above the hem reads as a mistake. Downtown, the move is a garment bag left at the office and a change at six. On the 504 in a long skirt, gather the fabric over your forearm on the steps, and check the back hem for grit before anyone photographs you.

The collar decides it before the tailor does

A dinner jacket's collar should sit flat against the back of your shirt collar with no daylight, standing and moving, and the shirt collar should hug your neck with a finger of room. Rented jackets gap there, cut for an average neck and somebody else's shoulders, and that gap is what the room reads without knowing it is reading. The luxury language quiz takes four minutes. Check yours in a mirror, with a second mirror behind you.

Common questions

What does black tie mean for a woman?

Black tie for a woman means a floor-length gown or a formal long dress in a fabric with weight: silk crepe, duchesse satin, velvet, heavy georgette. A well-cut woman's tuxedo is equally correct and has been since the 1960s. Choose jewellery for hard flash, where coloured stones and pearls beat pavé diamonds.

Can you wear a suit to a black tie event?

Yes, you can wear a suit to a black tie event, provided it is navy, charcoal or black, worn with a white shirt, a plain dark tie and polished black leather shoes. You will read as the guest who chose against a tuxedo, which at most Toronto galas passes unremarked. A patterned tie or brown shoes is where a suit stops working.

What does black tie optional actually mean?

Black tie optional means the host would prefer a tuxedo or a gown but will accept a dark suit or a formal cocktail-length dress. Nobody at the door is counting. Dressing to the higher end of the code has never been the mistake here.
