David Cameron said what matters "is not what politicians are wearing, but the ideas in the head and the actions that they are taking."
Asked whether it was "insensitive" that Theresa May had worn sparkly shoes and a Vivienne Westwood suit said to be worth £1,200 for her party conference speech, Mr Cameron said she gave "a great speech yesterday."
The Prime Minister continued: "This is a Home Secretary who has cut immigration, who has cut crime, who got Abu Qatada out of our country and back to Jordan.
"I think that's what matters most of all, not whether someone chooses to spend their money on shoes or a suit or what have you."
