The 16-year-old, nominated for this year's Nobel peace prize, said she is of the view that a woman should not cover her face in court or in other places "where it's necessary to show your identity".
"I don't cover my face because I want to show my identity," Malala, who considers herself a believing Muslim said.
Asked what she thinks of the burqa in the UK, Malala told the Guardian, "I believe it's a woman's right to decide what she wants to wear and if a woman can go to the beach and wear nothing, then why can't she also wear everything?"
The book recounts Malala's life before and after October 9, 2012, when a gunman boarded a school bus full of girls in Pakistan's Swat Valley and asked "Who is Malala?"

Then he shot her in the head.
"The air smelt of diesel, bread and kebab mixed with the stink from the stream where people still dumped their rubbish," Malala recalls.
One of her friends told her later that the gunman's hand shook as he fired.
Malala mentions more than once in her book that no one believed the Taliban would target a schoolgirl, even if that schoolgirl had been speaking and writing against the Taliban's ban on female education since the age of 12.
In her book, Malala writes of how her speech at the United Nations received plaudits around the world, but in Pakistan people accused her of seeking fame and the luxury of a life abroad.
