Petit Tresor is the pioneer in the Los Angeles shopping destination of Robertson and Melrose Place that includes Chanel, Oscar de la Renta and London's Soho House. Since its opening in 2002, this tiny shop full of treasures has quietly become the source for sophisticated mothers and those who shop for them. As its name suggest -- Petit Tresor is French for Little Treasure - the bounty in this boutique was soon discovered by celebrities Angelina Jolie, Gwen Stefani, Jennifer Lopez and Lisa-Marie Presley.
