Tony Abbott rates himself among the world's coolest dudes in politics and says he's got the threads to prove it.
The opposition leader almost constantly wears a "uniform" of pale blue tie, dark suit and white shirt.
On Thursday he defended his choice, saying blue was the coalition's traditional colour.
"I did notice a couple of years ago that Barack Obama and David Cameron, who are two of the coolest dudes in politics, tended to dress with a dark suit, a white shirt and a blue tie," he told Sydney radio 2SM's John Laws program.
"I thought well, look, if it's good for them it's probably good for me.
"If you've got more or less the same uniform on every day, people they just take it for granted and your appearance doesn't become something that people talk about."
Mr Abbott also denied using Botox, saying his secret to looking good was simply getting up early and exercising every day.
