"I see nothing wrong with celebrating women and their sexiness"
Gillan was criticised by some for supposedly being too sexy in the role of Amy Pond. She reprised her kissogram policewoman outfit in this year's Christmas special.
Speaking to Now, Smith said: "I know those short skirts caused a furore but I say bring them on. I see nothing wrong with celebrating women and their sexiness.
"There's absolutely nothing exploitative or demeaning about it."
The series premiere of Smith's first year as the Doctor was last week named as the most-watched programme on BBC iPlayer in 2010.
