Today, Crown Princess Mary opened the Golden Days Festival 2019. The Golden Days Festival aims to impart knowledge, history and culture. The theme of the festival this year is "1989" on the occasion of the 30th anniversary of several world historical events, including the fall of the Berlin Wall, the reunion of Europe and the birth of the Internet. The festival is developed in collaboration with more than 150 partners and attracts over 30,000 guests of all age each year.

Crown Princess Mary wore a new Carolina Herrera polka dot dress. She turned the matching belt into a collar and wore a new Max Mara black belt with the dress instead. She repeated her Gianvito Rossi black suede mesh pumps and her Quidam black clutch.
