Dame Joan Collins looked elegant as she joined late sister Jackie's daughters Tiffany and Tracy Lerman at the premiere of Lady Boss: The Jackie Collins' Story. 

The actress, 88, cut a chic figure in a white dress adorned with red roses which she teamed with a white jacket as she posed on the red carpet for the film about her sister's life, which screened in London on Thursday night.
