SAN FRANCISCO — Vivian Brown, one of the San Francisco twins whose colorful matching outfits and infectious smiles helped make them local celebrities, has died.

Barbara Farber, director of the assisted care facility where Brown lived for the past year, said that the 85-year-old Brown died in her sleep Wednesday.

Brown had suffered from Alzheimer’s disease.

The 5-foot-1-inch Vivian and her sister, Marian, were often seen walking arm-in-arm down San Francisco streets in carbon-copy outfits and eye-catching hats. They often stopped to pose for pictures with tourists and locals alike.

The pair for a time made money from appearing in advertisements, including spots for Dell Computer, Virgin Atlantic Airlines and Reebok.

Marian said she hoped to be buried in San Francisco next to her sister.
