Shop the Grey Trench Coats We'd Actually Wear Handpicked by Claire

Grey is the trench colour that gets overlooked in favour of camel or black, which is precisely why it earns its place. It reads softer than black, less predictable than camel, and it has the particular advantage of working with both warm and cool palettes without a fight. A good grey trench sits somewhere between stone and charcoal, never so pale it looks washed out under office lighting, never so dark it might as well be navy. The tone should have some depth to it, a hint of warmth or a slight chalky cast, rather than a flat, synthetic grey that can look cheap regardless of the price paid for it.

Construction matters more than colour once you have the shade right. Look for a proper storm flap, actual functioning belt loops rather than decorative stitching, and a collar with enough structure to stand up when you want it up and lie flat when you don’t.

Cotton gabardine is still the benchmark fabric because it holds its shape through a day of wear and creases in a way that looks intentional rather than crumpled. Avoid anything with too much stretch in the weave, it tends to cling and lose the clean line that makes a trench worth having.

Fit is where most people go wrong. The shoulder seam should sit exactly on the shoulder bone, not creeping down the arm, and there should be enough room through the body to layer a jumper underneath without pulling at the belt. Oversized has its place for a slouchier, off duty look, but a trench that swamps the frame stops doing its job, which is to look sharp over anything.

As for styling, it earns its keep precisely because it refuses to be precious. Worn open over tailoring it sharpens a work outfit instantly. Belted over jeans and boots it does the heavy lifting on a grey morning when nothing else feels right. It layers cleanly over knitwear for the transitional months and works just as well thrown over a slip dress for evening, when the practical outerwear suddenly looks deliberate. This is a coat for commuting, for travelling, for the in between days that don’t call for wool but demand something more considered than a jacket.
