Dior vs Reem Acra

Why must designers copy each other. As I was doing research for this weeks Cinderella Fantasy I came across the Fall 2010 Reem Acra Bridal collection. The finale of the show had me scratching my head, why you may ask? Well the Finale dress was almost an exact copy of a Christian Dior Couture gown from the Fall 2009 collection. While the dresses are not exact copies of each other, the Reem Acra gown is fuller and not as sexy but the similarities are unmistakable. The tired tulle skirt is about the same and the bustier with the dip in the center. Well if your not convinced then check it out for your self.
