Not a single audience member has asked about it, he says. Fashion commentators and other media also seem oblivious. Karl Stefanovic in his Burberry knock-off with co-host Lisa Wilkinson. Yet co-host Lisa Wilkinson still receives regular and unsolicited fashion appraisals, as she revealed in her well-received Andrew Olle lecture last year. ("Who the heck is Lisa's stylist?" one emailer demanded to know. "Today's outfit is particularly jarring and awful. Get some style.") These same viewers, however, have failed to observe – or simply don't care – that the man beside her happily slips on the same outfit, day after day. "No one has noticed; no one gives a shit," Stefanovic tells Fairfax Media. "But women, they wear the wrong colour and they get pulled up. They say the wrong thing and there's thousands of tweets written about them. "Women are judged much more harshly and keenly for what they do, what they say and what they wear."

His frustration at this, he says, sparked his experiment. Karl Stefanovic wearing the suit in July 2014. "I've worn the same suit on air for a year – except for a couple of times because of circumstance – to make a point. "I'm judged on my interviews, my appalling sense of humour – on how I do my job, basically. Whereas women are quite often judged on what they're wearing or how their hair is ... that's [what I wanted to test]." Stefanovic is a close friend of Samantha Armytage, co-host of rival breakfast program Sunrise.

Earlier this year, News Corp tabloid The Daily Telegraph dredged up old photographs of Armytage running errands in comfortable clothes, then published them because ... well, the purpose of the story was never entirely clear. "She's a mate and she was hurt by that," Stefanovic says, shaking his head. "And I can understand. You've got to have a thick skin in TV but there's a limit." He immediately offered Armytage his support, ignoring their professional rivalry. "I don't care who they are," he says. "It's a friend's duty to be there to try and ease the pain." He adds that while his eight-year on-air partnership with Wilkinson has had its ups and downs, their bond is now stronger than ever.

"What Lisa has done for women, in magazines and in television ... she's a great journo," he says. "We've had an amazing and enduring partnership. We've loved each other, we've hated each other and we've loved each other again. You have your ups and downs but I think that's normal! "It just so happens that our problems were vented in public. I don't care what anyone says out there: Lisa and my relationship is special and we love each other to death." There's one thing that's straining the friendship, though. Loading

"Only Lisa and [Today team member Sylvia Jeffreys] know about the suit. They often remark that it's getting a bit stinky. I'm hoping to get it into the dry cleaners at the end of the year." mlallo@fairfaxmedia.com.au
