Fashion Spotlight

So today, I'm working on my world history project (fashion in the 1900s) and I'm Googling pictures of different styles.  I was at the point where I was searching for vintage cocktail dresses, and I find this dress:

Pretty, right?  But my guess is you're thinking, Where is Emma going with this?
Well, I see the dress and it automatically reminds me of one a friend wore to a party last fall.  I went on Facebook to check, and I was right!  Kate wore a dress very similar to the one above, and neither of us even realized she was emulating the style of a 1950s-1960s cocktail dress.

Here's Kate's dress, so you can compare:

Different sashes, and the skirts fall differently, but there's definitely a similarity in the halter neck style and the overall look is reminiscent of the vintage cocktail dress.
