Legendary actress Diane Keaton’s autobiography Then Again hits the shelves on Tuesday.

In the intimate memoir the endearing star, of course, revisits her career-defining hit Annie Hall (1977) and her relationship with Woody Allen.

The film earned Diane style icon status as her personally-inspired Annie costumes; button down shirts, waistcoats, slouchy pants, neckties, fedoras and oversized blazers –sparked a major menswear trend.

Today, the androgynous look continues to resonate, albeit in a more tailored fashion.
