[Intro: why organic cotton is worth caring about, and what made each of these brands make the list.]

[Brand one]

[What they make, where they're from, and the one piece to start with.]

[Brand two]

[What they make, where they're from, and the one piece to start with.]

[Brand three]

[What they make, where they're from, and the one piece to start with.]

[A one-line takeaway in your voice.]

[Intro: why a good coat is the one piece you'll wear more than anything else you own, and what you looked for when choosing these.]

The forever coat

[The classic long wool coat in camel, black or navy that you'll still be wearing in ten years. What to look for in the cut and the fabric.]

The colour coat

[The one that makes the outfit for you: a colour you'd never pick for a jumper, but which works as the one bold thing over everything else.]

[A one-line opinion about coats, in your voice.]

The everyday jacket

[The shorter, easier one for days that aren't cold enough for the big coat.]

For years the safe answer was a wardrobe of oat, stone and camel. It's tasteful, but it's also a little asleep. This series is the opposite: one colour combination a week that shouldn't work on paper, and does on a person.

Why chartreuse and burgundy works

Chartreuse is loud and acidic; burgundy is deep and grown-up. Put them together and each one calms the other down. The burgundy grounds the brightness, and the chartreuse stops the burgundy from feeling too serious.

Pick one to lead, let the other one accent.

How to wear it

Easiest entry: a burgundy knit or trouser with one chartreuse piece, like a bag, a scarf or a pair of shoes. Braver: a chartreuse top with a burgundy skirt, and nothing else competing. Keep the rest neutral-dark (black, chocolate) rather than beige, so the clash stays the point.
