So apart from the colour issues, the looking best when you’re naked beneath it, and the fact that its major selling point (keeping you dry) isn’t always a given, what is good about the trench?
The fact that in the right shade, cut and fabric (showerproof ideally), it’s a wonderful piece of classy, androgynous kit. It also requires almost nothing in the way of accessories, other than long boots, slingbacks (if you’re aiming for the Christine Keeler vibe) or trainers.
The best trench fabrics are stiff enough to hold some shape and for the collar to stand up but not oppressively heavy. Or they’re artfully floppy – good if you’re wearing a sleeveless one as a dress. Unless you’re statuesque, opt for slimmer lines and a length that works not just on your frame, but with your clothes. Most trenches aren’t easy to take up.
Some Macintosh trenches have smart piping or detachable linings that make them much cosier, year round. Not cheap, but a long-term investment. Alexa Chung has done a wonderful waxed trench for Barbour. And the Jigsaw one I’m wearing here is a lovely olive-beige, showerproof, cotton twill, with a leather-look panel.
It’s worth stalking the resale sites, too: Hardly Ever Worn It for instance, has a good selection of Burberrys. Although even second-hand, they cost between £400 and £600 – a sign of how well they wear.
