- Leonora was invited to create a mask based on an endangered animal for The Animal Ball 2013, a royally attended event organised by conservation charity Elephant Family. The event was held in Clarence House, London, and was a huge success. Leonora’s creations were chosen from over 100 headpieces and masks to be worn by model Cara Delevingne, and Ruth and Mary Powys from Elephant Family. Other designers creating pieces for the ball included Diane von Furstenberg, Manolo Blahnik and Matthew Williamson. Leonora's work featured heavily in the press, including in Vanity Fair's centenary edition.
- After the success in 2013, Leonora was invited to create a range of 24 lemur-themed pieces for high profile guests at the 2016 Animal Ball. The ball was hosted by HRH Prince Charles, and Leonora was one of only 40 invited fashion houses alongside names such as Burberry, Chloe, Jimmy Choo and Philip Treacy.
- The 2016 Animal Ball was the biggest conservation event in Europe, raising over £1.7m for animal conservation charities.
- Leonora's feature headpiece entitled Heads and Tails was based on the ring-tailed lemur. It was shown in the Victoria and Albert Museum, the world's leading art and design museum, at the Conservation Couture exhibition for two weeks in the run up to the Animal Ball 2016.
- The pieces were displayed in the personal shopping department of Selfridges flagship department store on Oxford St, London.
- Heads and Tails was chosen to feature on the cover image of the V&A Museum exhibition page.
