Don’t get us wrong — we love The Secret Life of the Teenager’s Shailene Woodley, but she committed a major fashion faux-pas at The Book of Mormon’s Los Angeles premiere.

On Sept. 12, Shai walked the red carpet in leggings and a white T-Shirt with a neon pink graphic depicting the evolution of man. If we didn’t see the event’s background behind her, we would assume she was running errands or lounging around at home.

A quick glimpse at other photos from the event showed that most people wore dressier clothing — men in suits and women in gorgeous dresses — so she was clearly the odd one out.

But then again, 20-year-old Shailene is a young star, so maybe it’s OK for her to be casual.
