Mr. Blackwell, whose list of the Worst Dressed Women of the Year had become an annual TV institution since the dress designer introduced it in 1960, died Sunday of complications from an intestinal infection at the age of 86. Although the list focused on the clothing choices of leading celebrities, Blackwell, whose first name was Richard, once told the Los Angeles Times "Maybe I should have named the 10 worst designers instead of blaming the women who wear their clothes."
