"[3] Musically, "Hello Bitches" is as an intense, ferocious and playful hip hop and electronic track that features "tough-talking raps in both English and Korean".

[4][5] It has been described as a song that embodies CL's swag and charisma, featuring instrumentations of synthesizers, a heavy 808 bassline, and a strong trap hip-hop beat as the main axis.

[6] Christina Lee of Idolator praised the song, writing "it's as assertive as CL has ever sounded, with its schoolyard taunts at the hook and barbs rapped in Korean and English about how she rules the world.

Furthermore, Glasby asserted that "it's an aggressive, effective show of strength that no other female K-Pop star could do quite like Chaerin Lee does.

The tour kicked off on October 29, 2016 at the Hammerstein Ballroom in New York City and concluded at the Sound Academy in Toronto on November 14.
