We know that Monday morning can be a sombre occasion, especially when you've had a particularly great weekend - but is that really any reason to go into mourning?
Kim Kardashian favours black clothes
New research reveals that women favour black clothing on a Monday more than any other day of the week.
The study found that women generally wear darker colours early on in the week to match their moods after a weekend of fun and chill time. Women were three times more likely to wear black on a Monday than on any other day, results showed. And following the darker tones on a Monday, nearly half of women were more likely to opt for brighter clothes on a Friday.
The women stated however that black gives them a more work-focussed feel and they turn to brighter shades towards the end of the week as the weekend comes into sight and their moods lift.
Anna Clarke, head of womenswear buying for Tu at Sainsbury's, who commissioned the study, said: "The links between colour and mood are well established and looking vibrant can encourage the same feeling in the wearer.
"Black clothing will always have its place but embracing colour and being adventurous with your style can have added bonuses on our happiness levels. "Whatever the essentials a woman swears by, the results show that finding your confidence and the colours that work for you only grows with age."
And black was linked to greater confidence also with women overwhelmingly more likely to gain a boost in black- although the 'lady in red' effect does still ring true and proved the second most likely to inspire confidence.
Anna continued: 'The study shows the strength of correlation between how a woman feels and the colours she chooses to dress herself in. "Black is a very versatile colour and can help generate a working mind-set as the results clearly show but it's interesting to see that when it comes to feeling good and more positive a splash of colour really does make the difference. "There was a clear trend towards wearing more colour towards the end of the week and a visible boost to a woman's mood when wearing brighter colours."
