With the upcoming come back of girl group Nine Muses with their first mini album, “Sweet Rendezvous,” a second round of teaser jacket photos have been released.

The girls of Nine Muses have transformed into pin-up girls, which emphasizes their sporty, cute and sexy image. This round of photos have a complete different feel from their first vintage, “ticket girl” concept photos.

Nine Muses’ new track, “Ticket” accentuates their strong vocals with a “retro vintage” feel. “Ticket” has been produced by Sweet Tune, who has produced past big hits such as Infinite’s “Be Mine,” and Kara’s “Step.”
