"She's a winner, champion/Superhuman, Number One/She's a sister, she's mother. Open your eyes, just look around and you'll discover/You know/It's a woman's world and you're lucky to be living in it," read some of the lyrics adorned on the mini-length outfit.

Katy's red velvet mini dress from Balenciaga features a one-shoulder neckline, a full-length sleeve, a figure-sculpting silhouette, gathered design, a floor-length cape attached to the shoulder, and a lyric-embroidered train attached to the hem of the ensemble. The singer paired her bodycon look with sheer black stockings, black pumps, and silver hoop earrings.

Lastly, Katy opted for black eyeliner, mascara-adorned lashes, darkened brows, nude pink lip shade, and rouge on the cheeks to round off the glam picks. She left her silky, long tresses loose in a centre parting and styled the ends in soft waves.
