Fashion is a notable outside interest, as chronicled by The New York Times, who stated that Lewis is "giving Kanye West a run for his money as the music world's leading fashion dilettante." Twin Shadow was a featured musician in Levi's "Live in Levi's" ad campaign. Since 2010, Twin Shadow has served as a muse and composer for Dao-Yi Chow and Maxwell Osbourne, the designers of the CFDA-award-winning line "Public School NYC". In addition to composing music for Public School, George Lewis Jr. has modeled for the clothing brand, both on and off the runway.
Lewis is part of a lineage of artists who constantly experiment but still manage to create the soundtrack to people's lives.
