Emma Watson's debut fashion range is to show at an eco-festival run by the Prince of Wales.

The collection - for fair-trade label People Tree - will debut on September 12 at the Prince of Wales' A Garden Party to Make a Difference event.

Emma revealed: "I'm so thrilled that People Tree will be showing the spring/summer collection at A Garden Party to Make a Difference.

"I think the Prince of Wales' initiative is such a brilliant idea and I'm thrilled."

The garden party, which takes place at the Friary Court of St James' Palace in London, takes place over 12 days and features performances from comedians and musicians.

'Harry Potter' actress Emma has long been known for her love of fashion, and has previously admitted she took inspiration from her own style to create the People range.

She said: "I went through my summer wardrobe and thought, 'If I filtered this so that it was just the very basics, what would I want to keep?' The answer was cotton vests, easy T-shirt dresses, nice scarves to accessorise with and some lovely linen pieces.

"For the boys' range I've done hoodies, which I know they'll love. The clothes are very British, which is why we shot the campaign in an English country garden - it's all very strawberries and cream and tennis."
