I am not cleared about the theme for Vera Wang pre-fall 2012 collection that what she was tried to presented. She presented short dresses mostly along with some tail dresses. And the most influential feature through out her collection was that stockings that more or less gave an overall sporty look.
According to Temperley "the pre-fall 2012 collection is more dreamlike and ethereal and less Bohemian". All the dresses were very stylish and praise worthy. This brand become famous too due to Pippa Middleton. Because she wore a dress from Temperley on her sister's wedding reception.
