Theresa May has been accused of being "out of touch" with ordinary people after wearing designer leather trousers with a price tag of nearly £1,000.
The prime minster's outfit for a magazine profile raised eyebrows among some MPs.
Former Education Minster Nicky Morgan said it had been "noticed and discussed".
But May's supporters said it shows the unbalanced scrutiny faced by high-profile women and argued the focus should be firmly on her policies - not her fashion choices.
Mrs May was photographed wearing the "bitter chocolate" Amanda Wakeley trousers and Burberry trainers for a Sunday Times profile.
Mrs Morgan, who was sacked as Education Secretary by Mrs May, implied that the decision to be photographed in the outfit showed poor judgement.
"I don't have leather trousers. I don't think I've ever spent that much on anything apart from my wedding dress," she said.
Fellow Conservative Nadine Dorries hit back in a tweet claiming that the former leader David Cameron had also worn expensive outfits but seen no such sniping.
Mrs May brushed aside questions from a reporter over whether her clothing showed she was out of touch with the British public, saying she made a point of meeting people from all walks of life.
Speaking during an official trip to Bahrain, she said: "Look, I stood on the steps of Downing Street and said what I did about the importance of a country that works for everyone, because that is what I have heard from people as I have gone around the country, as I have met people in a whole variety of circumstances."
The Prime Minister is known for her brightly-coloured kitten heel shoes - and her fashion choices have often been the subject of scrutiny.
In the Sunday Times interview she revealed she does not have a stylist but often takes advice from her husband Philip.
