Brun graduated from The Hong Kong Polytechnic University with a Bachelor of Arts in Fashion and Textiles (Knitwear Design with Technology) in 2013. She did a summer course with Parsons Paris The New School in 2012.
Brun is the founder of independent design label and studio röyksopp gakkai, which produces its own fashion line, and focuses on art direction, styling and props. Her 2019 all season collection - “ALICE” was inspired by Hajime Satawari’s photobook “Alice”, and Lewis Carroll’s Alice’s Adventures in Wonderland. The röyksopp gakkai style is based on 18th and 19th century children’s clothes, with a touch of minimalism and weird-cuteness.
