Katy Perry turns 41! A look back at her most unforgettable fashion moments

Katy stunned on the red carpet in a futuristic silver gown at the Breakthrough Prize ceremony. The dazzling, sculptural piece featured intricate beadwork, dramatic cut-outs, and a face-framing built-in hood. With slick waves and minimal makeup, the singer channeled a modern-day screen siren - proving her flair for high-fashion drama hasn’t faded one bit.

Throwing it back to her "I Kissed a Girl" era, Katy embodied pure pop whimsy in this candy-colored tulle dress at the 2011 People's Choice Awards. The strapless frock - a swirl of purple, pink, and blue - perfectly captured her playful stage persona. Paired with hot-pink pumps and her signature pin-up curls, it remains one of her most charming early looks.

Never one to shy away from color, Katy lit up the room in this neon-yellow fitted ensemble with gold detailing and matching metallic heels. Her rainbow ponytail added a signature twist, perfectly complementing her playful look. It’s a reminder of why she’s long been pop’s reigning queen of fearless fashion.

Katy embraced her inner space goddess in a shimmering silver corset bodysuit and thigh-high metallic boots. Topped with sculptural antlers, the look was theatrical and otherworldly - a perfect reflection of her high-energy stage persona. 

Katy turned heads in a strapless emerald green gown at a Painted Turtle charity event. The flowing silk dress, detailed with subtle embellishments and a thigh-high split, was both elegant and refreshing. With old-Hollywood waves, nude heels, and a statement necklace, she showed her ability to balance glamour with effortless sophistication.

The singer shimmered under stage lights in a silver mini dress designed to look like a mosaic of mirrored tiles. Paired with thigh-high boots and her trademark confidence, the look was pure disco fantasy - proof that 41 or not, Katy still knows how to make every moment sparkle.
