Katy Perry's latest look proves it's a woman's world.

While attending her first Balenciaga runway show during Paris Fashion Week Haute Couture on June 26, Katy made a grand entrance as she donned a giant black fuzzy coat with larger-than-life collars.

But instead of covering up, she left the jacket open to show off her underboobs and abs. 

However, the "Roar" singer—who shares 3-year-old daughter Daisy Dove with Orlando Bloom—opted for some modesty when it came to her bottom half, wearing low-rise ripped nylons that were layered over her heels. A slicked-back bun, barely-there makeup and Matrix-inspired sunglasses tied her look together.

"I wanted to be streamlined, sexy, sensual," Katy told Women's Wear Daily at the show about her bold outfit. "I wanted to wear my nylon right above my c-section scar. That's the lowest I was gonna go. Right there."

She summed her style perfectly, adding, "Simple but chic."

Of course, Katy has been taking Paris Fashion Week by storm.

To kick off the fabulous festivities on June 23, the former American Idol judge made a surprise appearance at the Vogue World: Paris show. While strutting her stuff on the runway, Katy bared it all in dominatrix-style dress by Noir Kei Ninomiya.

The see-through design featured geometric cutouts all over that looked like an elaborate harness, as well as peach-colored floral embellishments on the bottom half.

Two days later, the 39-year-old turned the streets of Paris into her own personal runway, as she exited The Ritz Hotel in a red-hot dress that included a massive train with the lyrics of her unreleased single "Woman's World" emblazoned on the back.

Katy isn't the only star to showcase her fierce style. Keep reading to see celebrities' fabulous looks during Paris Fashion Week Haute Couture.
