Keira Knightley Engagement: What Has The Enigmatic Star Been Wearing All Year? (PHOTOS)

Bet you didn't see this one coming: Keira Knightley is engaged! The British celeb has finally made it official with boyfriend of fifteen months, James Righton, a keyboardist and singer for the Klaxons.

The news comes as a bit of surprise -- not because we didn't realize she was dating anyone (although that's somewhat true), but rather because we simply haven't heard or thought about Keira in a while. The British actress, stunning on the red carpet and impossibly talented off-screen, manages to stay off the tabloid radar and fly undercover when not promoting her latest flick.

So what has Keira been up to these past several months (besides falling in love with Righton)? Keeping her simple, flawless fashion sense intact. You won't see a wardrobe malfunction from the likes of Keira Knightley -- girl likes her dresses opaque, with sleeves and perfectly formfitting (i.e. not too tight).

In honor of Keira Knightley's engagement, here's a look back at the star's recent style picks. Now the lookout for the ring begins...
