Old Money Formal Wear for Men, From Black Tie and White Tie to Classic Formal Outfits

Traditional shapes

Black tie and white tie have changed slowly, so a classic dinner suit can stay in use for many years.

Choosing traditional shapes, such as a one-button jacket with peak or shawl lapels, avoids the cut dating quickly.

Careful construction

Look for cloth that drapes well, neat stitching and a jacket that keeps its shape, whatever the label or price.

Natural fibres such as wool and mohair are traditional for dinner suits, although fibre alone does not guarantee a garment will wear well.

Quiet luxury

Traditional formal wear avoids visible branding and embellishment and relies on cloth, cut and fit.

This is a style preference, not a statement about money or values.

Small details

Formal dress codes leave little room for variation, so small details such as studs, cufflinks, the pocket square and well-polished shoes stand out.

Keep them simple and make sure they work together.

Correct fit

Fit matters more in formal wear than almost anywhere else, because the garments are plain and the lines are clean.

Ready-made dinner suits usually need altering at the sleeves, waist and trouser hem; made-to-measure and bespoke are options if your budget allows.

Main formal garments, shoes and accessories

These are the traditional garments for black tie and white tie.

Formal clothes

The single-breasted dinner jacket comes in black or midnight blue wool, barathea or a wool-mohair blend, traditionally with one button, peak or shawl lapels faced in satin or grosgrain, and jetted pockets without flaps.

A double-breasted dinner jacket, in black or midnight blue, usually has peak lapels and four or six buttons; it is worn buttoned, with no cummerbund or waistcoat needed.

The dress shirt is white, with a turndown collar, a pleated or piqué front and double (French) cuffs for black tie, or a stiff piqué front, wing collar and single cuffs fastened with links for white tie.

Formal trousers match the jacket, with a braid of silk or satin down each outer seam, no turn-ups, and a rise high enough for the waistcoat or cummerbund to cover the waistband.

Formal shoes

Black patent leather Oxfords or plain, highly polished black calf Oxfords are the usual choice.

Patent opera pumps with grosgrain bows are the most traditional option for black tie and white tie.

Velvet slippers are traditionally worn at home or at relaxed evening events hosted at home rather than at formal events elsewhere.

Formal accessories

The bow tie is self-tied, in black silk to match the lapel facings for black tie, or white piqué for white tie.

With a single-breasted dinner jacket, wear a cummerbund or a waistcoat, never both; the cummerbund pleats face upwards.

For shirt studs and cufflinks, choose plain black or mother-of-pearl studs with matching cufflinks.

Pocket square. White linen or silk, folded simply.

On watches, traditional black tie guidance notes that visible wristwatches were not worn with formal evening dress, while pocket watches were acceptable; many men now wear a slim dress watch that slips under the cuff.

The dinner jacket and shirt form the base, and the accessories should support them rather than compete.

For example, the sheen of satin lapels works with patent dress shoes, and a plain white shirt shows off simple studs and cufflinks.

How to dress for each dress code

White tie

White tie is the most formal evening dress code.

The black tailcoat is cut away at the front to end at the waist, with two tails at the back.

The white piqué waistcoat should not show below the front of the coat, so high-waisted trousers held up with braces are usual.

The shirt has a stiff front, a wing collar and single cuffs fastened with links, and the trousers carry braid down the outer seams.

Patent shoes or opera pumps complete the outfit.

Black tie

Black tie is the usual dress code for formal evening events.

The dinner jacket is traditionally black or midnight blue with peak lapels or a shawl collar, and notch lapels are generally considered less formal.

The trousers match the jacket and have a single braid down each side.

The shirt has a pleated or piqué front and double cuffs, and a cummerbund or waistcoat covers the waistband with a single-breasted jacket.

Black tie optional

A dinner suit is welcome, but a dark charcoal or navy suit is also acceptable.

With a suit, wear a white dress shirt, a plain or quietly patterned tie and polished black Oxfords.

Creative black tie

Creative black tie allows a personal twist on the traditional outfit.

A velvet dinner jacket in burgundy or forest green, or a jacquard jacket, is a common choice, worn with black dinner trousers and traditional accessories.

Semi-formal

For semi-formal events, wear a well-fitting dark suit in charcoal or navy worsted wool with a white or pale blue shirt.

A plain or subtly patterned silk tie and black or dark brown Oxfords complete the outfit.

Adding a personal touch within the dress code

Subtle pattern suits black tie, where a dinner jacket in a jacquard or textured cloth adds interest that shows only close up.

Colour. At creative black tie events, a burgundy bow tie or midnight blue cummerbund introduces colour without breaking the outfit.

For texture at semi-formal events, a flannel suit or a shirt in a fine herringbone weave adds depth.

Vintage accessories. Inherited or vintage cufflinks or a watch chain add character.

Modern cuts work for less strict events, where a slimmer dinner suit or a slightly shorter jacket can look more current while still meeting the dress code.

For important or very traditional events, the classic version is the safer choice.

Formal wear for spring

For a daytime wedding or formal lunch, choose a light worsted wool suit in soft grey, single-breasted with two buttons and notch lapels.

Pair it with a white cotton poplin shirt with a spread collar and double cuffs.

A subtle Prince of Wales check in the suit cloth adds texture.

Wear a soft grey two-button suit, a white poplin shirt, a pale blue silk tie with a small pattern, a white linen pocket square, silver cufflinks, black Oxfords and a slim watch on a leather strap.

Formal wear for summer

For black tie in hot weather or a warm climate, an ivory dinner jacket with a shawl collar is a traditional choice.

Wear it with black dinner trousers with a satin or silk braid, and a white shirt in light cotton with a pleated or marcella front and turndown collar.

Pair an ivory shawl-collar dinner jacket with black braided dinner trousers, a white marcella-front shirt, a black silk bow tie, plain studs and cufflinks, black patent Oxfords and a white pocket square.

Formal wear for autumn

For creative black tie or a relaxed evening event, a burgundy velvet dinner jacket with a shawl collar or peak lapels is a warm, seasonal choice.

Pair it with black dinner trousers and a white shirt with a pleated front and double cuffs.

Choose a burgundy velvet dinner jacket, black dinner trousers, a white pleated-front shirt, a black silk bow tie, onyx studs and cufflinks, a black silk cummerbund and black patent opera pumps.

Formal wear for winter

For black tie in winter, a midnight blue double-breasted dinner suit in a wool and mohair blend or barathea is a classic choice.

The jacket has satin-faced peak lapels and is worn buttoned, so no cummerbund or waistcoat is needed.

Wear a midnight blue double-breasted dinner suit, a white pleated-front shirt with double cuffs, a black silk bow tie, black patent Oxfords, a white silk pocket square in a straight fold and a black overcoat with a white silk scarf for the journey.

Tailoring for formal wear

Good tailoring helps formal garments sit cleanly and move with you.

Ready-made dinner suits can look just as good as made-to-measure once they have been altered at the sleeves, waist and hem.

Do

Have formal wear altered to fit, since ready-made, made-to-measure and bespoke can all look good when the fit is right.

Choose classic shapes, which stay usable for many years of events.

Check the cloth and construction, because a well-made garment holds its shape and is more comfortable in a warm room.

Keep accessories simple. A slim watch, plain cufflinks or an inherited tie pin is plenty.

Follow the invitation’s dress code, as it tells you what the host expects.

Don’t

Wear clothes that do not fit. Poor fit shows more in plain formal garments than in casual clothes.

Rush into fashion-led cuts for occasional wear, which can date quickly.

Judge by fibre content alone. Some synthetics look shiny under evening light, while some blends wear well, so compare the cloth in person.

Over-accessorise, because too many accessories distract from a simple outfit.

Guess the dress code. If the invitation is unclear, ask the host.
