The Duchess of Cambridge has turned out to be a loyalist to a gown and has flaunted it at different occasions.

She just wore an ink-blue empire-waisted, off-the-shoulder Jenny Packham gown for the third time in just over a year, reports peoplestylewatch.com.

She wore it Tuesday night for a dinner. The first two occasions were for a formal dinner here in October 2013 and the National Portrait Gallery gala in February.
