She looks very much like.....

I thought she was sasha grey

I'm with the OP, Olivia Wilde for sure

Nope. OW's facial structure is crazy weird. Beautiful, but odd.
This Daisy person -- pretty, striking in some ways, but I'm not impressed with her SW character.
Olivia > Ren

Daisy looks like:

Keira Knightley
Hayley Atwell
Lena Headey
and her sister Kika Rose Ridley

Agree ... and that's a good thing.
I have no fondness for this SW iteration, but they could have done worse in the looks department. She's alright.

She looks very much like a dirty, dirty girl who likes to do bad, bad things.
