Tuxedo vs Suit: How to Tell Them Apart

A tuxedo is evening wear finished with silk details: lapels faced in satin or grosgrain, covered buttons and a braid down the trousers, worn with a dress shirt, a black bow tie and polished shoes. A suit is made in one cloth from lapel to hem and works anywhere from the office to a party. The quick test: look at the lapels. If they catch the light with a silk facing, it is a tuxedo.

Lapels, colour and cloth: the first giveaways

On a tuxedo, the lapels are faced in satin (glossy) or grosgrain (ribbed silk), contrasting with the matt body of the jacket. The classic lapel styles are the shawl and the peak. A notch lapel does turn up, but it is considered less formal because it belongs to the suit.

On a suit, the lapels are in the same cloth as the jacket, usually notched, with peaks reserved for more formal suits. A shawl lapel almost never appears on a business suit.

One point worth stating plainly: a black suit is not a tuxedo. Without silk facings and trouser braid, it remains a black suit, however similar it looks at a glance.

Colour and cloth differ too. A tuxedo is black or midnight blue, in a matt cloth such as barathea or a wool-mohair blend that lets the silk lapels stand out; the ivory jacket is reserved for evenings in hot climates. Suits come in a far wider range: navy, grey, brown, stripes and checks, in anything from fine worsted to tweed. Colour and surface alone will often tell you which garment you are looking at.

Buttons, pockets and vents

A single-breasted tuxedo traditionally has one button at the front. The buttons are covered in the facing silk, or made of black horn, never metal. A suit usually has two buttons in horn or plastic matched to the cloth.

Tuxedo pockets are jetted, without flaps, because flaps belong to outdoor and daytime clothing. Suits usually have flap pockets, sometimes with a small ticket pocket above. As for vents, the traditional tuxedo is ventless; side vents are widely accepted today. A suit may have a centre vent or side vents depending on style.

Trousers: braid and no belt loops

Tuxedo trousers are cut from the same cloth as the jacket, with a single braid of satin or grosgrain running down the outside seam. Black tie takes one braid; white tie tailcoat trousers traditionally carry two.

Tuxedo trousers have no belt loops and no turn-ups. They are held up by braces or side adjusters, with the waistband hidden under a cummerbund or waistcoat. Suit trousers have belt loops and may have turn-ups. Our navy tuxedo with satin trouser stripe shows the braid clearly.

Shirt, tie and waist

A tuxedo is worn with a white dress shirt with a pleated or piqué bib, a turndown or wing collar, and double cuffs for cufflinks. Many dress shirts close with studs rather than ordinary buttons. A suit takes a business shirt, with button or French cuffs as you prefer.

At the neck, a tuxedo calls for a self-tied black bow tie in the same silk as the facings. A suit takes a necktie. The tuxedo's waist is covered by a cummerbund or a low-cut waistcoat; a suit may have a matching waistcoat cut higher, or none at all. Our black shawl-lapel tuxedo with pleated shirt and black studs shows the complete picture.

Shoes and accessories

A tuxedo goes with patent leather oxfords or opera pumps with a grosgrain bow, and fine black socks in silk or wool. Add a white pocket square, and cufflinks and studs in onyx or mother-of-pearl. A suit is far more forgiving: oxfords, derbies or plain loafers, a belt, and whatever watch you like.

When to wear a tuxedo, when to wear a suit

A tuxedo is evening dress: invitations marked black tie, evening weddings, galas and formal dinners. Wearing one in the daytime runs against traditional convention. A suit suits daytime weddings, corporate events, cocktail parties, or any invitation without a stated dress code. If you are unsure, check our dress code guide or read our tuxedo styling rules.
