He went on to say that she "influenced the timbre of the sound" and assisted the production as if "she's making a movie." Composition Perfectionist is a concept album which focusses on how perfectionism influences Kills. "All the songs revolve around my ambition, celebrations, frustration and disappointments of being a perfectionist", she stated. "I think we're all perfectionists – we're all looking for the best to fulfil our ideologies and dreams." Kills was also inspired by "women's obsession" with fashion in general. She described the album's sound as "dark pop" due to its "opinionated" and "confrontational" lyrics which, according to her, differ from mainstream music. The lyrical content is occasionally comical and uses metaphors frequently. Perfectionist is an electropop and synth-pop album, characterised by "driving rhythm sections and edgy minor-key melodies".

The song's chorus features Kills singing in a falsetto note. Writing for Consequence of Sound, Alex Young opined that the song discusses "the duplicity of identity, hubris, and objectification". "Not in Love" is styled in electronica and influenced by acid house. AllMusic writer Jon O'Brien wrote that it "provides a welcome respite from the album's constant floor-filling leanings". On "Acid Annie", Kills plots a revenge on an ex-boyfriend, while on the synthpop track "Superficial", she confronts her "consumptive impulses" and appreciation of "finer things."
