Dress down Friday. Casual clothes day. Can't be arsed to wear a suit or shave today day. Call it what you will, but it's become an accepted part of Australian life, especially for office workers.
And I can see the attraction. Shirts, ties, shiny shoes and sharp suits are all very well, but sometimes they're just a touch uncomfortable, a little bit constrictive and not what we want to be wearing from long before nine til way after five. Surely rolling out of bed into some trainers, a sloppy top and some comfy pants makes everything easier, makes the whole work experience, for one day in five at least, fun and enjoyable.
You think so? You big sucker.
In that new ABC comedy - the one about a couple of slackers mooching about Melbourne - one of the characters insisted in a job interview: "I want paid lunch breaks. I want casual clothes day. I want holiday pay. I want a swipe card for the building.”
C'mon. Work is work. Take it seriously. And what's more, take yourself seriously. I'm of one mind with my wife who has always said that you have to get dressed in your work clothes or you don't feel like working.
And don't forget that casual Friday is just an idea dreamt up in an HR department somewhere as a way of keeping the drones happy. You know what keeps me happy? A pay rise. A promotion. Some likelihood that my services will be required for the next few years.
Being allowed to dress slightly less formally on Fridays isn't that great an incentive. Don't get fooled. It's a con job. A big fat lie. Do the police have a casual clothes day? Farmers? Surgeons? "Sterile gown, mask and hat Mr Butcher?" "Not today nurse, it's Friday. I'll remove this spleen in my chinos and Seaworld T-shirt."
So thank goodness it seems to be petering out. At New York Fashion Week earlier this year Bill Cunningham, apparently a world-renowned fashionista and photographer with The New York Times, declared "dress down Friday is dead."
Let's hope so, but while it's here how do you deal with it? Do you just turn up as normal and pay no attention to the whole thing - my approach of choice - or do you join in? And if you are going to go casual, how casual do you dare to go?
Melbourne image consultant Bronwyn Fraser says that in her experience most people enjoy dress down Friday, but she cautions that companies "need to be better at conveying what's acceptable and what's not".
Thongs? "No." Shorts? "No, neither for men or women." T-shirts? "OK as long as they're not covered in logos." Jeans? "Fine as long as they're clean and not too 'distressed'."
And there's some bad news for companies too. What you wear, Bronwyn says, "affects how you think, work and act" and, she told me, there have been surveys in the UK that show the relaxed mindset that casual Fridays bring has a detrimental effect on productivity. "People seem to be starting their weekends a bit earlier than they might," she says.
There are, it must be said, few funnier sights than the drunken salaryman, tie askew, shirt unbuttoned and suit crumpled, asleep and dribbling on the last train home. He's missed his stop and he'll be walking home in the rain later. But surely even more laughable is the thought that a day when you don't have to wear that shirt, suit and tie makes the daily grind any less Sisyphean.
What do you think? Is it time to bury dress down Fridays? Or is there something still to be said for an office full of the casually clothed?
