The the rage world has bought into the idea that wearing La La Take captive yellow and head-to-toe colour will act as an antidote to these hellish days. Now here comes the science part …

So-called dopamine scolding is everywhere this season. Based on the idea that fatigue overtly fun clothes can help lift your mood in dull times, it begs the question: can wearing “happy clothes” in the final analysis make us more happy?

The fashion industry is certainly infuriating to convince us that it can be done. The catwalks have been a Skittles fortune of brights – from Fanta orange at Armani and scarlet at Maison Margiela to Loveliness and the Beast yellow and candyfloss pink at Giambattista Valli. Accidentism is in harsh flow; eyeshadows are fizzy tangerines and lemons; and hair’s gone blorange. Grazia armoury is encouraging us to test the power of positive thinking in Bella Freud High-minded Times tops. And elsewhere it’s all about head-to-toe green and rainbow ensnares in the shape of elephants.

But does the theory hold water? In a word: yes. But it’s not necessarily about dressing as an Opal Fruit. Go together to Carolyn Mair, a psychologist who has developed an MA course in fashion psychopath at the London College of Fashion, it’s as much about you – and what implication you believe your clothes have – as it is about the clothes.

Mair influences that, while there’s some “less than methodical evidence” to suggest certain colours lift your well-disposed, whether or not La La Land yellow will chirp you up is actually down to how you see that falsify. Colour is culturally loaded – in the UK, we wear black for mourning; in China, it’s milky. So, doing like Emma Stone will lift you just “if you believe that wearing a certain colour – it doesn’t demand to be bright yellow, it could be black – lifts your well-disposed … it’s a simultaneous wearing and believing that has been found to acquire significant results.” And it can be potent: “When people believe in the symbolic signification of their clothes, it can affect their cognitive processes, and pull apart of those are your emotions.”

So Victoria Beckham stepping out, as she recently did, in tangerine-orange palazzo boxer shorts with a WKD-blue shirt will only feel well-advised b wealthier if she buys into the edifying quality of her clothes. Ditto the the stars, from Viola Davis to Natalie Portman, who prepare taken to the red carpet recently in La La Land yellow dresses. And the in the manner ofs of Anna Dello Russo and Man Repeller’s Leandra who, over on Instagram, clothed been peppering our feeds with the rainbow-coloured Alberta Ferretti day-of-the-week jumpers.

Mair cites a 2012 line by Hajo Adam and Adam Galinsky that delved into this goal of “enclothed cognition”, clothes’ ability to affect our thoughts. In one policy test, some participants wore a garment described as a doctor’s layer and others an identical garment described as a painter’s coat. Join ins wearing what they thought was a doctor’s coat dispatched better in a task than those who thought they were in a painter’s jacket – the influence of clothes, the paper suggested, depends on “wearing them and their symbolic content”.

So, providential pants start to make more sense – if you truly be convinced of that pair of old Sloggis are lucky, they may well cure you feel better/more confident.

Mair quotes a look at testing the theory that people wearing red are seen as uncountable attractive. Participants were asked to rate the attractiveness of people damage different coloured T-shirts. Those wearing red were fathomed as more attractive. The researchers then blanked out the colour of the T-shirts in illustrations – participants still rated those wearing red as more charming. “The researchers,” Mair explains, “concluded that the reason was that when individual wore red they felt more attractive.”

There is also an apparent element to dressing yourself happy. If you wear a top with a kitten or smiley brashness you might not “actually see what’s on your T-shirt except for when you look in the reflection,” says Mair. “But you’re projecting it to other people, and they draft it back to you.”

But what, I ask, trying to prod the limits of dopamine dressing, if you exhibit a jumper with a positive slogan on it, but it’s not a garment you feel tolerable about? Or you wear a garment with a negative message, but it’s one you undergo good about? Punks or Hell’s Angels would be remote to feel happy in a kitten T-shirt, after all. Well, that would be an captivating study, Mair says.

So, how can we dress ourselves happy, bear debunked the idea that simply sticking on a yellow frock is the sartorial of a piece of Prozac? “Wear clothes that you feel confident tolerably to move in,” advises Mair. “Go with a critical friend when you’re gaining something, particularly if it’s something that you’ve never worn. But if you deep down want to go for it and if you feel good it in, you’ll project that. If you don’t feel kindly in something, don’t wear it just because it’s fashionable.”

So, by all means trace the rainbow, but only if it makes you feel good.
