Copy Cat?

Instead of posting about who I thought was best dressed and who failed miserably at the Oscars, I have decided to post about a dress I had found earlier today online. Recognize It?

No? How about this one?

The first is vintage Christian Dior from his fall 1949 collection, you can find it in The Met archives. The second was worn by Miley Cyrus at Sundays Oscars, her dress was by Zuhair Murhad.  Am I the only one who finds them eerily familiar?
