London Fashion Trends: The importance of the little black dress

I was thinking in doing a post about little black dresses. Inmediately after, I realised how obvious that post would be. I guess for me, a little black dress is a way of escape from reality, because it does not matter how many I have, I always need another one. Because it's the answer when you are about to go and you don't know what to wear. Because, honestly, when do you feel better than in a LBD?

Because all the fashion icons know about the importance of the little black dress. I'd like to know what meaning has for you the Little Black Dress.
