SWERVE COTTON KNITWEAR

It will look fine in the shop but will turn into heavy, saggy, baggy, belly hammocks after one wear. Merino wool has “memory” and is much more flattering and lighter.

SLEEVES

Make like Ryan Gosling and learn to roll up your shirt sleeves in a crisp fold line and ordered manner that takes the wide French cuff above your elbow… but no higher. No guns on show, please.

BEWARE OF BISCUITCOLOURED SUITING

Anything from Rich Tea to Digestive. It’s frumpy, fattening and daytime TV presenter-ish. More Geoffrey Boycott than Don Draper.

LOOK LIKE YOU BELONG

So, when in Rome, wear expensive loafers with no socks, Dickie Greenleaf double-breasted blazers and knitted ties. If you are in Santa Eulària des Riu, Ibiza, assume the loose-fitting, white-on-white, hippy jim-jams of the older locals.

IT’S ALL ABOUT FIT

So, no Towie tight pants in July. Go roomier, lighter and unstructured. Have your trews and blazers maintain a certain cut and dash that suggests the hand of a tailor not a drunken mail order.

SHORTS

Leave the cargo cut-offs for hiking and let Juergen Teller’s boys have those yellow, Seventies porno star, highcut jobs to themselves. Best to stick to a plain, flatfronted Bermuda cut.

MIAMI VICE

The muted, pastel-toned “cocaine cowboy” style affected by undercover cops Crockett and Tubbs in TV show Miami Vice was a huge menswear moment back in 1984 and it’s a big look again in 2018, too. Only a little less roomy… and no parachute shirts.

DENIM

Thanks to Timothée Chalamet in Call Me by Your Name, jean jackets are pale and washed out. Denim trousers are faded and light blue.
