"If Looks Could Kill" is a song by American rapper Destroy Lonely. It was released on March 3, 2023, through Opium and Interscope Records, as the lead single from his debut studio album of the same name. Lonely recorded the song in October 2022 with producers Clayco, Ssor.t and Carter, and credited it with establishing the album's direction. A departure from Lonely's rage sound, "If Looks Could Kill" features rock, emo, and pop-punk-influenced production featuring moody guitars and hazy vocals. Over a three-chord riff, Lonely proclaims himself a "fashion demon" and juxtaposes lyrics about fashion and violence whilst discussing his expanding wealth, evolving fashion tastes, and personal demons.
