Melbourne, Nov 9 More than half of the Aussie blokes have admitted to wearing the same undies for at least two days, a new survey has revealed.

Almost one in 30 men have old undies and admit that they would rather spend the money on beer than buy their underpants.

One in 14 respondents have also admitted to wearing women's frillies.

The Galaxy survey showed that nearly 400,000 Aussie men owned just four pairs of underwear or even less.

Carl Urbani admitted he had "never bought a pair in my whole life", but had more than enough to find fresh ones each day.

"I used to get 12 pairs at a time from Nanna," the Daily Telegraph quoted him as saying.

Retired tennis player Pat Rafter, who endorses 'Bonds' undies, says men who don't change daily are disgusting.

"In my opinion, if you're wearing really old undies, you may as well not be wearing any at all," he said.

"Ensuring your family jewels are well supported and hygienically cared for should remain high on the list of priorities for men," he added. (ANI)
