Outfit guides by occasion

Each guide explains what to wear and shows complete outfits (suit, shirt, tie and shoes) put together by our stylists, with a link to every item.

Which suit for which occasion?

What should the groom and groomsmen wear?

A 3-piece suit (jacket, waistcoat, trousers) is the classic choice for the groom. For a summer wedding choose cream, light blue or a linen suit; for an autumn, winter or countryside wedding choose tweed or herringbone in tan, brown or green. Groomsmen usually wear the same suit in a different colour, or the same suit with a different waistcoat or tie. For a black-tie wedding, choose a tuxedo.

What should a man wear to a wedding as a guest?

A 3-piece or 2-piece suit in navy, grey, blue, burgundy or tweed is a safe choice. Avoid white, ivory and cream unless the couple asks for it, so you don't compete with the groom. For summer and beach weddings, a linen suit keeps you cool; for autumn and winter weddings, tweed and herringbone look right and keep you warm.

Prom and black-tie events

"Black tie" on an invitation means a tuxedo: a black or midnight navy dinner jacket with satin lapels, matching trousers, a white wing or turn-down collar dress shirt, a black bow tie and polished black Oxford shoes. For a prom, a coloured tuxedo (blue, burgundy) or a slim 3-piece suit also works. See the tuxedo collection for single- and double-breasted and shawl-collar styles.

1920s, Peaky Blinders and Gatsby themed parties

Looking for a Peaky Blinders costume or fancy dress outfit? We sell real tailored suits and accessories, so the look is authentic and can be worn again. For a Peaky Blinders / Tommy Shelby look: a tweed or herringbone 3-piece suit, collarless (grandad) shirt, newsboy cap and a long wool overcoat. For a 1920s gangster or mafia look: a pinstripe 3-piece suit, a tie and a fedora-style hat.

Office and business

Navy, charcoal and grey suits are the safest choices for the office, interviews and business events. A 2-piece suit is enough for everyday work; a 3-piece adds polish for meetings and presentations. In autumn and winter, a navy or grey tweed suit looks smart without being stiff.

Smart casual, date night and going out

Smart casual means no tie and no full suit, but still sharp: a linen or knitted shirt, tailored or linen trousers, and suede trainers, loafers or Chelsea boots. For a date night, add a blazer or wear a tweed suit with a turtleneck instead of a shirt and tie.
