Spring is a difficult time for us hapless humans and our curious habit of putting on clothes.
While the blossom is blossoming and the lambs are lolloping and the birds are beginning to sing in perfect harmony with the world around them, we're at our least comfortable and – frequently – worst dressed.
Whether it's finding yourself shivering outside a pub at 8pm in only a polo shirt or awkwardly carrying a thick scarf around during a burst of spring sunshine, the default look for many men during these months is 'ill-prepared'.
But in spring, we offer you only one. The biggest style mistake of them all. The error that costs the most during March, April and May.
Not checking the weather.
Sounds simple, doesn't it? Blindingly obvious. And yet so many men wake up on a spring morning and attack the day based on little more than what they see out of their window and what side of the bed they got out of.
Feel positive, and it's on with the light summer blazer. Feel cowed by life and it's reach for the thick overcoat. The problem is the weather doesn't give a damn about your inner mood and will backfire on you accordingly – probably every other hour.
A quick morning scan of what lies ahead – or rather, above – puts you back in control. If the weatherman says scattered showers, go for a technical jacket that's lightweight and breathable but – crucially – waterproof.
If it's going to be bright but breezy, accessorise with a lightweight scarf that will keep the chill out without making you sweat.
If the temperature is set to drop dramatically in the evening (it probably will) and you're planning a night out, accept you're going to need a second layer and a pair of socks.
Equally, if the spring weather is going to do a 24-hour impression of summer or winter, you bust out that linen suit or revert back to the safety of your parka accordingly.
Basically, other than investing in a great bomber jacket, buying some quality knitwear and learning to layer properly, the most important rule for spring is to take your style cues not from Idris Elba or Daniel Craig but the world's meteorologists.
And you thought they were just men in shiny suits.
