Kristen Stewart was photographed departing Los Angeles on Wednesday night, bound for Toronto, where she'll make her much-anticipated red carpet return at the city's annual film festival for her flick On the Road.

Still dealing with the aftermath of her shocking July 17 makeout session with director Rupert Sanders, the 22-year-old star looked somber and casually-clad as always. Yet again, however, Stewart's seemingly tossed-on ensemble seemed to send a very clear message.

Wearing spectacles and skinny jeans (and iPod earbuds), Stewart wore a white V-neck "Irie" t-shirt identical to one worn by estranged beau Robert Pattinson last year.

In an earlier post-scandal outing, Stewart similarly wore her Twilight costar's baseball cap, backpack and a meaningful gold ring he recently gifted her with.

Despite her cheating shocker, friends of the estranged pair remain optimistic about their future prospects together. "Their mutual friends think they will get back together," one source told Us Weekly.
