Pretty Little Liars is unpredictable, we know that. But even so, one thing we did not expect from the Season 3 winter season is to see the normally glammed-out Hanna (Ashley Benson) rocking overalls.

PLL writer Lijah Barasz tweeted this photo on Friday (September 14), saying, "Hanna's overall cuteness! #PLL Ep 3x18" She later tweeted another photo of Ashley in the same outfit, this time interacting with Tyler Blackburn (Caleb Rivers).

Ashley herself also tweeted a pic of herself in the outfit. This time she's lying on the floor. "I fell asleep. They took pictures," she explained.

So, what can we learn from these photos? Because Lijah describes the outfit as "Hanna's overall cuteness," we assume it is, in fact, a costume. And given that farmyard chic isn't Hanna's usual style, we're guessing there's a special occasion — especially because in the photo Ashley posted, we can see she's even wearing real, useful books. We didn't know Hanna owned those!

We're thinking that Hanna's outfit might link to the fact that we're supposed to find out something about Caleb's (Tyler Blackburn) past in Season 3, Episode 18. A visit to his real family's home? Or maybe they're tracking down "A" clues in odd places...

What do you make of Hanna's outfit? And do you think it's cute?
