Peter Dutton sparks cost of living uproar after eagle-eyed Aussies spot extraordinary detail about his outfit

Opposition Leader Peter Dutton's choice of neckwear on the campaign trail has sparked a cost of living row three days out from the election

The Coalition leader was questioned over his pricey fashion choice after he was spotted wearing a $600 tie from a luxury Italian menswear brand at a Melbourne charity on Wednesday, where he packed boxes for families in need.

Mr Dutton was conducting a press conference afterwards when a reporter noticed he was wearing a tie from designer label Zegna.

'Mr Dutton, what's on your tie?' they called out as he wrapped up the press conference.

He did not respond to the question and walked away.

Mr Dutton was still wearing the tie when he sat down with Chinese community leaders and later when he dropped by patisserie in Bayswater. 

But there was no sign of the flashy attire when he later filled up at a petrol station on the EastLink freeway.

The specific design of Mr Dutton's tie is not currently listed on the Italian brand's Australian website, but it is available on Zegna's Thailand store.

Similar silk ties are on sale on the brand's Australian website for around $605.

The Italian menswear label is also a favourite of former Labor Prime Minister Paul Keating, who was rarely seen in anything but a double-breasted suit. 

Mr Dutton has repeatedly declared during the election campaign that he wants to stand up for working class Aussies.

He has also criticised Prime Minister Anthony Albanese for failing to address the cost of living crisis.

However, Mr Dutton came under fire during the final leaders' debate on Channel Seven on Sunday night when he caught out over the price of eggs.

The two leaders were asked about the cost of a dozen eggs.

The Opposition Leader grossly under-estimated the price when he said 'about $4.20' while Mr Albanese was closer in nominating $7.

The most recent online price were $8.80 at Coles and $8.50 at Woolworths.

Some commenters were not impressed with Mr Dutton's answer.

'It was really shocking to see how out of touch someone can be with a carton of eggs,' a member of the studio audience commented.
