There's competition in the stands as well as on the courts at the Virginia Slims of Florida tennis tournament under way in Boca Raton.

While Jennifer Capriati, Steffi Graf and Gabriela Sabatini are going at it on the court, designer Oleg Cassini will be checking out the audience daily and presenting a $1,000 gift certificate to the most fashionable fan.Cassini says he's not necessarily looking for the best-dressed person but "the most beautiful, most elegant and best put together."
