Emma Watson will unveil her collaboration with People Tree at Prince Charles's Garden Party to Make a Difference next month.
The Harry Potter star has helped design clothes for the fair trade fashion company, reports the Evening Standard.
Watson said: "I'm so thrilled that People Tree will be showing the spring-summer collection at the garden party. I think the Prince of Wales's initiative is such a brilliant idea and I'm thrilled."
The Garden Party To Make A Difference will take place in the gardens of Clarence House, Lancaster House and Marlborough House this September.
Watson will not be able to attend the event as she has to return to the US for university.
