Here's What We Have Covered In This Article
What does black tie actually mean?
Black tie refers to a formal evening dress code, typically worn after 6pm. In the UK, it means a dinner jacket (also called a tuxedo), a formal white shirt, black bow tie, black trousers with side braid, and smart black shoes.
The basics include:
-
Dinner jacket in black or midnight blue with satin or grosgrain facing
-
White formal shirt (usually with Marcella or pleated front)
-
Black bow tie, ideally self tie
-
Waist covering (cummerbund or low cut waistcoat)
-
Black trousers with silk side stripe
-
Formal shoes, usually patent leather or well polished calf
You may also find invitations using terms like “evening dress” or “tuxedo required”, all of these fall under black tie expectations. For weddings, galas or London charity dinners, black tie is still very much expected.
How should a black tie dinner jacket fit?
The dinner jacket is the centrepiece of the outfit. Look for a structured fit that flatters your frame and keeps clean lines. Key features include:
-
Lapels: Peak or shawl are correct; notch lapels are too informal
-
Facing: Satin or grosgrain material on lapels
-
Cut: Single breasted with one button is most traditional. Double breasted styles work if they fit properly
-
Sleeve length: Should show about half an inch of shirt cuff
Avoid hiring if possible. Fit and proportion are key, and rental jackets often miss the mark. If you must hire, choose a place that offers tailoring adjustments.
If you’re aiming for a classic tuxedo fit, make sure the jacket hugs the shoulders without pulling and the waist is neatly tapered.
Pro Tip 1: A poorly tied bow tie is more obvious than you think, practice before the event.

What shirt, bow tie and studs do you wear?
A black tie shirt should have a formal front:
-
Marcella bib (waffle textured panel) or pleated front are both correct
-
Collar: Wing collar or classic spread. The wing collar is traditional but can look theatrical if worn poorly
-
Cuffs: Double cuffs with cufflinks
-
Studs or buttons: Use shirt studs for the front if your shirt allows
Bow ties should match the lapel material and be self tie. Pre tied versions are often too neat and obvious.
Studs, cufflinks and your watch (if worn) should have matching metal tone with silver or gold, not both.
Pro Tip 2: If your shirt shows beneath your jacket button, you’re missing a waist covering..
Should you wear a waistcoat, cummerbund or neither?
If your dinner jacket is single breasted, always wear a waist covering:
-
Cummerbund: Sits at your natural waist and hides the trouser waistband
-
Low cut waistcoat: Covers the same area, adds a structured shape
You can skip the waist covering only if your jacket is double breasted and remains buttoned throughout. Without a covering, your shirt can become visible beneath the button line when seated or moving.
What trousers and shoes are correct?
Trousers should match the jacket and have a silk side stripe:
-
No belt loops
-
Flat front or very subtle pleats
-
Proper hem length (avoid puddling)
Shoes should be black and formal:
-
Patent leather oxfords are traditional
-
Highly polished calf leather is acceptable
-
No brogues, loafers or open lacing
Pair with long black socks. Never show ankle or wear patterned socks with black tie.
These trousers are part of a full tuxedo set, and skipping formal shoes or socks can break the entire look. Don’t risk looking out of place.

What accessories actually matter?
Accessories make or break the look. Focus on refinement:
Do:
-
Wear a clean white pocket square (linen or silk)
-
Match your cufflinks, watch and studs in tone
-
Choose a slim dress watch, or no watch at all
-
Use discreet shirt studs if your shirt allows
Don’t:
-
Wear a belt with black tie trousers
-
Use a clip on bow tie
-
Mix gold and silver metals
-
Over accessorise with pins or flashy jewellery
The goal is balance and quiet polish, not over accessorising.
Should you rent, buy or go bespoke?
-
First time wearing black tie? Renting is acceptable, but seek high quality fit and consider adding your own shirt and accessories
-
Attend a few events a year? Buying an off the peg dinner suit and having it altered is a strong choice
-
Regular guest or hosting formal events? Bespoke is worth the investment
Some tailors also offer made to measure services, which sit between off the peg and full bespoke. Fit is always the priority as a mid priced suit that fits beats an expensive one that doesn’t
How to dress for black tie in summer or winter
-
Summer events: Choose breathable fabrics like tropical wool or unlined jackets. Consider lighter weight shirts
-
Winter occasions: Velvet jackets or heavier wool can work well. Add silk scarves or structured overcoats for travel to the venue
Climate and venue matter so opt for comfort without compromising the formal requirements
Common mistakes to avoid
-
Wearing a belt with dinner trousers
-
Choosing notch lapels instead of peak or shawl
-
Shirt collar collapsing under lapels
-
Visible undershirt through the shirt bib
-
Wearing coloured socks or short socks
-
Pre tied bow tie that looks too stiff
-
Overloading with loud cufflinks or jewellery
A well executed black tie outfit is subtle and confident. Keep it clean, balanced and classic
Can I wear a coloured bow tie to a black tie dinner?
Technically, no. The tradition is to wear a black bow tie. Coloured bow ties, even in silk or velvet, are usually considered a creative or themed variation. Stick to black unless the event specifically allows variation
Final checklist before leaving the house
-
Shirt pressed and lint free
-
Bow tie symmetrical
-
Shoes clean and polished
-
Jacket shoulders lie flat
-
Trousers hemmed to the right length
