Confession: We have an unhealthy obsession with Stana Katic's hair. (And Stana Katic in general, but we like to keep our creep-factor on the d/l, so don't tell anyone).

The Castle beauty usually wears her long, brown locks loose and wavy, but sometime she opts for a classy up-do, especially if she's on the red carpet.

We can't figure out which style we prefer — the up-do shows off her stunning neckline, while the long waves give her a soft, romantic vibe — so we're leaving this one up to you guys.
