Dowling told The Sun: "They are changing the look this year and it was suggested I could wear jeans. I said I would love to wear jeans.
"They then said, 'You looked really brown'. So I have been told to be less Essex, more Chelsea. How that is relevant to the show I don't know but, yeah, I have to look less brown."
Speaking of being mugged earlier this year, he added: "Even now I don't go out when it is dark on my own. When it happened I left the lights on and I was crying for my mum. I felt like a bit of a pussy."
Dowling concluded by saying that Big Brother, which starts its new series on June 5, "still has such a strong following".
