Allison Williams enjoyed her second night out in a row at the UNICEF Snowflake Ball held at Cipriani 42nd Street in New York City yesterday evening.
Like Katy Perry, Allison also wore a Naeem Khan Spring 2013 gown.
The ‘Girls’ actress selected an aqua lace long-sleeve gown with shimmering silver appliqués.
Her flawless look was simply enhanced with a Bulgari silver ring and Bulgari diamond stud earrings.
Tumbling tresses, kohl-rimmed eyes which made her baby blues pop and pink glossy lips completed her look.
