Diane Keaton wasn’t just a Hollywood legend — she was instantly recognizable for her wide-brimmed hats, turtlenecks, and perfectly layered outfits. While her fans admired her distinctive and timeless fashion sense, the deeper reason behind her signature look was profoundly personal. After her passing on October 11, 2025, those close to her revealed that her carefully chosen wardrobe was about much more than style — it was also her way of protecting herself.

Keaton had lived with skin cancer for most of her life, beginning with a basal cell carcinoma diagnosis at the age of 21. The illness ran in her family, and she had seen loved ones endure difficult treatments. Later, she faced additional battles with squamous cell carcinoma, which required multiple surgeries. Her preference for hats, turtlenecks, and long sleeves wasn’t simply a fashion statement — it was a practical safeguard against the sun and a constant reminder of the importance of skin health.

Beyond physical protection, Keaton often shared that her wardrobe brought her emotional comfort. In interviews, she explained that dressing in layers helped her manage insecurities and gave her confidence in the public eye. Her hats, especially, became a source of reassurance — a familiar detail that made her feel composed and in control. Despite her fame, she never relied on revealing styles; instead, she chose clothing that reflected her individuality while offering both safety and self-assurance.

In her final months, Keaton continued to encourage others to care for their skin, emphasizing the importance of sunscreen and protective clothing. She once said she never stepped outside without SPF 50. Today, her signature style is remembered not only for its elegance but also for what it represented — resilience, self-care, and quiet strength. Diane Keaton’s hats and turtlenecks remain enduring symbols of grace, courage, and authenticity.
