Since becoming hat designer to such stars as Christina Aguilera and Brad Pitt, Fiona Bennett has achieved fame on an international scale. She produces her unusual headgear at her salon. Through the large shop window in Tiergarten passerbys can watch her felting, sewing, draping and embroidering. Each hat is a unique, handmade creation and can, on request, be personally fitted to the customer’s head by Ms. Bennett herself.
