Doe-eyed

[Sonia]

Innocent or naive.

[Tanya Shivari]

some women, like does, have beautiful brown eyes

[Sarah]

Eyebrows that are naturally higher-set in an innocent question mark with a blank expression; wide eyes yet with low, sleepy eyelids.

[Jessica]

Josie McCoy from Josie and the Pussycats.
She is the very DEFINITION of the word.
More accurately, it is the actor that portrays Josie, Rachael Leigh Cook, who is the doe-eyed beauty. But its this movie that accentuates her big brown eyes the most.
