In the 1990s, Shelley Hack began focusing on other ventures and started taking a more political role in women's causes. She became active in the National Women's Political Caucus and became a member of The Westside Women's Health Center Advisory Council (The Westside Women's Health Center offers a preventive and education-based approach to providing health care for more than 8,000 at-risk women and their families each year). She also started delving into grassroots politics in L.A. In October of 1994, Shelley attended the Hollywood Women's Political Committee's "Making a Difference" luncheon which was held at the Regent Beverly Wilshire Hotel in Beverly Hills, California. Other celebrities in attendance were Shirley MacLaine, Liza Minnelli, and Linda Gray. In November of that year, Shelley was featured in the "What People Are Wearing" section of the celebrity tabloid The Star, as the "Blast From The Past" entry... which featured a pic of Shelley from her Charlie's Angels days and a pic of her from the 1994 luncheon. Shelley's chic black skirt suit and crisp white shirt outfit accessorized with a large gold brooch was occasion appropriate.
