Emma Watson and British fair-trade fashion label People Tree are getting ready for a royal showing of their spring/summer 2011 collection.

The "Harry Potter" actress, who counts fashion as one of her passions, launched the "Love from Emma" line earlier this year to wide praise. The collection, which gives a percentage of sales to UNICEF, features an eco-friendly range of jersey T-shirts, dresses, woven skirts, trousers, shorts and knitwear for both men and women.

To show off the new line, Watson and People Tree have been invited to Prince Charles' A Garden Party to Make a Difference — a series of cultural events to promote sustainable living. While she won't be in attendance, the 20-year-old will make a special introduction via video.

“I’m so thrilled that People Tree will be showing the spring summer collection at A Garden Party to Make a Difference,” she said in a statement. “I think The Prince of Wales’ initiative is such a brilliant idea and I’m thrilled.”

The 12-day Garden Party event will take place at Clarence House in London — and will mark the first time that Prince Charles' private organic gardens will be open to the public. There will also be exhibitions, interactive displays and a host of activities and live performances all dedicated to the green scene.
