The actress, 44, recently held a question and answer session at the Everyman cinema close to her London home and she talked about the response she got to her outfit for the event, which she teamed with odd shoes.
She said: "I am not Hannibal Lecter wearing someone else's skin. Why does it matter? I make do with what is in my wardrobe. I think one should but I receive comments that that's not good enough.
"I think one can wear the same thing, in this day and age especially. There are too many awards, no other profession gets so many. There are millions of people who deserve awards.
"That's what I have a problem with and the fact it's now hijacked by the fashion industry - it's all what you wear."
