Riverdale Gotham City Sirens Captivating Snapshots

On Instagram, Riverdale stars Madelaine Petsch, Lili Reinhart, and Camila Mendes shared a photo of them as Poison Ivy, Harley Quinn, and Catwoman, respectively. The photo was captioned “Gotham City Sirens.”
Madelaine Petsch Poison Ivy Outfit


Embodying the essence of Poison Ivy, Madelaine Petsch dazzled in a striking green bodysuit that effortlessly accentuated her incredible figure, showcasing her bust and embracing her natural curves. The suit wasn’t just a statement of color; it was a celebration of form. Intertwining around her, like nature reclaiming its space, were meticulously crafted vines, adding depth and authenticity to her ensemble.
The pièce de résistance, however, was undoubtedly her natural red hair, which cascaded with a fiery elegance that synergized immaculately with the character’s iconic look. It wasn’t just a costume; it was as if Poison Ivy herself had stepped out of the comics and into reality, courtesy of Petsch’s impeccable portrayal.
Camila Mendes Catwoman Outfit


While the world has seen various interpretations of the enigmatic Catwoman, Camila Mendes opted for a homage to the legendary Eartha Kitt’s portrayal of the feline femme fatale. Cloaked in a form-fitting all-black ensemble, Mendes captured the very essence of stealth and allure that the character is known for. The outfit was paired with a glistening gold necklace, offering a subtle nod to the luxury and opulence Catwoman so often finds herself entwined with.
Although Mendes chose to forego Kitt’s classic mask, she made a contemporary statement with the addition of the signature cat ears, a staple of the Catwoman identity. The overall look was nothing short of sensational, with Mendes channeling the grace and mystique of Gotham’s most iconic cat burglar.
Lili Reinhart Harley Quinn Outfit


Riverdale’s sweetheart, Lili Reinhart, took a delightful twist from her girl-next-door image to embody the mischievously iconic Harley Quinn. Drawing inspiration from the classic Batman Animated Series rendition, Reinhart showcased the character’s flamboyant style in a latex body suit, a captivating blend of red and black that effortlessly hugged her frame.
The ensemble, further enhanced by its bold cleavage, was both daring and true to Harley’s audacious nature. With this outfit, Reinhart didn’t just wear a costume; she became Gotham’s vivacious vixen, proving once again her versatility as an actress and her impeccable sense of style.
Is a Gotham City Sirens Movie in the Works
In 2021, James Gunn, co-president and Co-CEO of DC Studios, mentioned that he wasn’t actively developing a Gotham City Sirens film. While Gunn did acknowledge previous discussions with Harley Quinn’s actress, Margot Robbie, about collaborating again, he confirmed that the topic of GCS never came up. Recently, Karen Gillan, notable for her role as Nebula in Guardians of the Galaxy, showed interest in portraying Poison Ivy within Gunn’s DC Universe slate. Yet, as of now, Gunn’s intentions regarding this iconic Batman adversary in the DCU remain a mystery.
