Nick Kyrgios was found in breach of Wimbledon's all white policy in Friday's victory against Milos Raonic, bizarrely warned for wearing the tournament's official headband.
Kyrgios, who wore the headband in the second set, was told by the umpire that it didn't meet the tournament's requirements because of the purple and green strips running across it.
The Australian then turned it inside out, which was all white, and wore it for the rest of the match.
Despite what seemed like a pedantic request from the chair umpire, Kyrgios was in no mood to talk about it in the press conference.
After turning it on the third set, Kyrgios was asked if it was the headband that inspired him.
"No," he replied bluntly.
"Did the headband help?," the journalist asked.
"No," Kyrgios responded.
"Was it a tip to anyone?" the reporter continued.
Once again, "no" was his answer.
It was a bizarre opening to the press conference after such a jovial performance to topple the No.7 seed, who knocked Kyrgios out of last year's quarter final.
Another journalist proceeded to ask about the headband later in the press-conference, also asking for the Australian's thoughts on the tournament's dress code.
"I like it," Kyrgios said.
"What kind of question is that?"
"They told me to turn it around, so I turned it around."
It comes a day after Roger Federer, who was banned from wearing orange-soled shoes in 2013, complained about Wimbledon's crackdown on the all-white policy, which was recently changed from predominantly white.
'We're talking white like it was in the 1950s. If you look at the pictures then, it was all white," Federer said.
"I still have the pictures in my mind where Edberg and Becker and all those guys, they had more colour. They wore iconic T‑shirts.'
"White, white, full-on white,' he said. 'I think it's very strict. My personal opinion: I think it's too strict."
Kyrgios had some help in his win against Raonic from an unlikely source of inspiration - the man in the Batman t-shirt.
"Yeah, he was just a fan, you know," Kyrgios said.
"I thought he was key in the match. He was actually saying some really good things at crucial moments. I think he helped."
