When I saw Mischa Barton wearing this Marchesa Fall 2010 dress at the “Artists for Peace and Justice Party” in Cannes last night, I heard a crashing sound in my head.

That was the sound of my dreams being shattered.

This was my favourite dress from the Marchesa Fall 2010 collection because the embroidered cream duchess satin carousel cocktail dress was so beautiful and different from anything Marchesa had presented before.

I had hoped to see this stunning dress worn by Camilla Belle, Emmy Rossum or Leighton Meester (notice they are all brunettes), but that may never be realised now.

I gave Mischa a pass yesterday, but she gets an almighty fail today.

How can something so beautiful and delicate be made to look so very bad?

Without a hint of exaggeration, I’m devastated.
