Out in public, the star appeared in a white denim jumpsuit with high-waisted wide leg trousers and a matching cropped Ganni button down jacket.
Leni began to collaborate with the brand, so her appearance at a fashionable party was not accidental.
The girl completed her look with white Fila sneakers on a high platform.
Her hair was cut into a stylish bob and re-dyed a light shade, and her face wore light daytime make-up.
