Fashion student Pauline arrived at the grand Hôtel Salomon de Rothschild with her friend Margaux Fouchere, who brought along her adorable dog.
The stylish duo and their furry friend then took their places in the front row to see French designer Alexis Mabille's Autumn / Winter designs hit the catwalk,
The collection seemed to capture Pauline's imagination and she was seen taking pictures on her mobile phone as the models walked the runway.
