First came the Carrie nameplate necklace, worn by Sex and the City's Carrie Bradshaw. Then arrived the initial pendants bearing the letters of the wearer's name. And today's hottest new neck accessory? New York designer Alex Woo's Little Numbers line, worn by stars such as Kelly Ripa, Eva Longoria and Hilary Duff. Stars don their digits of choice, which hang from delicate silver or gold chains or suede cords. Ripa wears a 3 to represent her three children. Longoria sports a 9 in honor of the jersey number of her boyfriend, Tony Parker of the San Antonio Spurs. Celeb mom Courteney Cox has a 1 and 3, symbolizing daughter Coco's birthday June 13.
