Eva Mendes (left), a ray of sunshiny ruffles in a strapless Bill Blass frock at the Dec. 4 London launch party for The Spirit, is No. 10. "I love color and try not to fall into the black trap," she says.

"It just feels so pretty," Taylor Swift (center) told Life & Style at the Grammy-nominations concert on Dec. 3 in LA. How pretty? Her violet chiffon Jay Godfrey confection earned her No. 8 on the list.

A J. Mendel-clad Lucy Liu stunned at the UNICEF Snowflake Ball in NYC on Dec. 3 in one of the season's hottest hues: cobalt blue. She's No. 3.
