Kristen Stewart is still embarrassed about an outfit she wore when she was 11.

The Snow White and the Huntsman star still smarts when she thinks about her styling at the premiere of 2002's Panic Room - one of her early movies - which consisted of a long black trench coat over a green dress and blocky trainers.

"My biggest fashion regret? I think the pictures that they took at the premiere of Panic Room. It's like a popular image to show from when I was younger, you know, like, 'She was a kid!' And I look at that and I'm like, 'Oh... my... gosh.' It shouldn't be embarrassing because I was so young. But it doesn't even matter how young you are, you're just so, so embarrassed," she said.

Kristen, now 23, admits she was "completely goofy" as a child, and even hates her hair in the pictures. "I had like these baby hairs and I was being weird about them, so I was like, 'I'm just gonna cut them off.' And I had like these little things like poking out from under my hair and behind my ears, and a ridiculous outfit. I did not know how to get dressed up at that age at all, I didn't even know what I liked. I was just like completely... a goofy kid," she added.
