At the 2025 Met Gala, Chimamanda made a bold statement in a showstopping red gown designed by Prabal Gurung, who also accompanied her up the Met steps. With feathers adding drama and a bold train trailing behind her, the gown also paid homage to the evening’s theme, “Superfine: Tailoring Black Style,” with its sharp, menswear-inspired details, including a cinched waist and statement bows. She finished off the look with diamonds that perfectly complemented the striking silhouette.

 Adichie joined a diverse group of influential figures, including Simone Biles, André 3000, Janelle Monáe, and Usher, in shaping the event's direction and theme.

Ahead of the night, Chimamanda posted a photo on Instagram Stories of the Met Gala towel from The Plaza placed next to her new book, “Dream Count.” The caption read: ‘Happy Met Monday.’

The gala's theme, "Superfine: Tailoring Black Style," celebrated Black dandyism and its impact on fashion and identity. The accompanying exhibition, inspired by Monica L. Miller's book "Slaves to Fashion," explored the cultural and political significance of Black menswear from the 18th century to contemporary times.

Adichie's inclusion in the host committee underscores her global influence beyond literature. Known for championing African designers through her #WearNigerian movement, she has consistently used her platform to spotlight Nigerian and African creativity on the international stage. Her participation in the Met Gala further cements Africa's growing impact on high fashion and cultural narratives.

While specific details about Adichie's attire at the gala have not been publicly disclosed, her history of making bold fashion statements suggests she likely embraced the event's theme with a look that celebrated African craftsmanship and style. Her previous collaborations with fashion houses like Dior and her commitment to promoting Nigerian designers indicate a continued dedication to integrating fashion with cultural identity.

Adichie's presence at the 2025 Met Gala not only highlighted her multifaceted influence as a writer and cultural advocate but also emphasized the significance of African representation in global fashion events.
