Jenny Agutter likes wearing a wimple on 'Call the Midwife' because she can "tuck her face in".
The 66-year-old actress - who is best known for portraying Sister Julienne on the hit BBC drama - likes to pull the strap of the cloth headdress because she can see her face "starting to fall", but she isn't too worried about wrinkles.
Jenny told Good Housekeeping magazine: "I have lines, lots of them but do you know what, I don't mind. We should all enjoy every line we've got on our faces, because we've earned each one.
"The part that worries me is when your face starts to fall. I can see it starting to happen to mine, so I just try to work around it.
"The best bit about wearing a wimple for 'Call the Midwife' is that you can just pull the strap round and tuck your face in it!"
Jenny - who has a 28-year-old son Jonathan with her husband Johan - claims she has no plans to go under the knife because she is "too squeamish" for surgery.
She said: "I'm too squeamish for cosmetic surgery. I've also seen the results of it and the forms that people have signed; you've no idea what's going to happen while you're under anaesthetic.
"If there was a new invention that guaranteed to keep you muscles doing what they should, that would be a different story ... sign me up."
The 'Railway Children' star also believes women can "absolutely" be sexy as they mature.
She said: "Age expectations have certainly changed. When I was growing up there was a 'twinset and pearls' age that you go to: Women hit middle age, cut their hair short and got their cardigans out.
"That's just not the case anymore. Look at someone like Tina Turner, who's both extraordinarily attractive and an extremely sexy person. She's carried on being sexy right into her 70s! It's about having a sort of naughtiness and an enjoyment of things."
