It's Chanel (obvs).
It's "Look 38" from their Fall/Winter 2014/15 collection.

I love it. I want it copied by the high street. IMMEDIATELY! I'm looking at you ASOS...
This frock, as seen on My Girl Crush Of The Moment Lupita Nyong’o at the MTV Movie Awards is probably the best dress I've ever laid eyes on in my 32 years of living.
