When it comes to beauty, some celebrities love to get dressed up and walk down the red carpet — but, for Jennifer Garner, she feels the most comfortable wearing nothing but jeans and a T-shirt.

“I try so hard to get out of [them],” she said about her red carpet attire in a new interview with People, covering their Most Beautiful issue for 2019. “But sometimes the day just doesn’t give you a break to shower and put on my other uniform, which is jeans, a sweater and sneakers.”

Jen’s kids don’t like her all glammed up either. When she gets home, they like her to be “the best possible version of myself,” the 47-year-old revealed. “They’ll look at me and say, ‘Can you wash your face? Can you put your hair in a ponytail and put your glasses and sweats on?’ And I see the compliment in that. They just want me to look like Mom.”

Ever since Jen was a kid, she was never into girly things like beauty and makeup. “Looks weren’t a big deal in my family. I don’t think my parents ever said, ‘You’re pretty,’ and so we just didn’t think about it,” she recalled. Although Jen described her childhood fashion sense as “band geek-chic,” she admitted that she never felt insecure about her looks.

“I was so not one of the pretty girls that I just bypassed insecurity and didn’t see myself as attractive at all. It was not part of my life,” she said. “I felt good about myself back then! That is the lucky trick.”

Admiring her own natural beauty was something Jen was really good at, so she never felt the need to cover her face in makeup. “Do I seem like someone who’s good at applying makeup?” she laughed. “I own the nicest brushes and I own contouring things. If I used it, I would just look bruised.”
