Rebecca's collection was quite young, fresh and mod. I called her collection young because i think the dresses were less lady like and more devoted to grown up girls like 20+ who wanted to look more modern and glamorous.
Just Cavalli never leave glamor behind. The collection overall looked resembling like from past but with modern touch. The prints, printed pants, feather, bell bottom pants were looked like some old pieces with glam glam touch.
Alexander Wang Pre-Fall 2012 collection was all targeted hard. This is because he strictly rely on men's wear fabric and stitching. But still with men's touch in the collection all models were wear feminine look.
