Katherine Schwarzenegger, daughter of Arnold Schwarzenegger and Maria Shriver, recently hosted a party for Fashion’s Night Out at Diane von Furstenberg in Los Angeles. The theme was “Trust Your Senses” and guests got to sample the designer’s new fragrance, Diane, before it hits stores in October, according to USA Today.

A percentage of the night’s sales went to benefit Best Buddies International. The nonprofit organization, created by Katherine’s uncle Anthony Shriver, is a global volunteer movement that creates opportunities for people with intellectual and developmental disabilities.
