Isaac turns to Alexander's retrospective exhibition for inspiration and decides to create 11 designs based on the theme of mental health.For Isaac, who has Asperger's and has experienced being bullied, this theme inspires him and his friend Alice to create 11 incredible designs for his catwalk pitch.
