Gillian Anderson used to be too "exhausted" to make an effort with her appearance.
Anderson 45, says she is embarrassed when she looks back on some of her sartorial choices at the height of her fame in 'The X Files' and even though she hated her look on the sci-fi show, she couldn't be bothered to change when she wasn't filming.
She said: "The odd thing is that even when I was put in those horrible pastel Lycra suits, there wasn't a single part of me that considered saying, 'Woah, wait one second.'
"Likewise with the hair, I was made to have red hair, styled in a particular way, but you'd have thought I might have done something with it off screen. Still, I didn't bother because I was so exhausted.
"So for nine years I went to work and was somebody else, without devoting any time or attention to the way I looked.
"Now, when I look back at images of myself in those horrible fashion decisions with my weight fluctuating all the time, I can't believe it."
Gillian admits she can see a lot of herself in Kristen Stewart, who is often criticised for her surly expressions.
She told Britain's Glamour magazine:" Do you know what's funny? Sometimes I'll see photographs of myself in the early days of 'The X Files' and I think my attitude to the whole thing was very similar to Kristen Stewart's.
"There's a very similar look in my eye, slightly defiant, slightly bored. All I ever got was, 'Smile! Smile!' when I didn't want to smile. And I really wish somebody at that time had told me, 'You know that it's OK to be who you really are.' "
