Keira Knightley. The shape of her face and the dark hair reminds me of when Keira was younger.

They also seem to have the same body type. The features are a tad different though.
I checked every "look likes", and none of them got nowhere near as Emily Blunt! They're almost twin. Crystal is maybe a younger version of her. I'm amazed and i love them both.
Check these two pics:

Only thing similar I see is hair and eyes. =(
shareI don't see Emily Blunt at all. Someone said the girl from Ferris Buellers Day off (the girlfriend) and I can definitely see that and she kinda looks like Rooney Mara (minus the creepy piercings). And because I'm lame she kinda looks like Demi Lovato.

She looks nothing like Rooney
Jasper's Moodswingers
All good calls
shareI don't personally think she looks like any of the above.
I've always thought she looked like Alex Steele (Tori Santamaria from Degrassi).
Alex is slightly darker than Crystal, but their facial structure, hair, voice, even dimples, are similar. When I started watching teen Wolf, I actually thought it was Alex.
