She is Sarah Brandner (Germany, 1988), she is Bastian Schweinsteiger's ex - girlfriend.
She met Bastian in a private social event when she was young, but nothing happened then. Some years after, they met again in Ibiza when both were in holidays. Then, they went out some times and started to date.
Sarah is one of the most famous models in Germany and is one of the most loved Wags.
She attended Obermenzinger Gymnasium, where she completed her abitur in 2010 doing mathematics and economics. Then she started studying sociology and history of art at the Ludwig Maximilian University of Munich, but broke it off.
She became a model sort of by accident, like many models she was discovered on the street. Where an agent saw her and asked if she would be interested in modeling. At first she wasn't sure, because she was only fifteen years old.
She is a super model and I love her style. Is smart, useful and glamurous. She wears dresses, jeans, leggins, and so on, with a mix of colours and styles for every moment: classy, sport, chic...
She wears J Brand, Michelle Mason, ASOS, Chanel, Jimmy Choo, Faith Connexion, Manolo Blahnik, Alexander Wang, Valentino, Stella McCartney, Diane Von Furstenberg, Yves Saint Laurent, Christian Louboutin, HOMIÉS, as far as we know.
