She has never been one to hold back with her fashion, both on stage and on the red carpet.

And Katy Perry certainly showed no signs of stopping on Monday, as she embarked on another energetic tour show in NYC in an array of striking ensembles.

The singer, 32, slipped her enviably leggy figure into a raunchy leather leotard and thigh-high boots, as she belted her hits at the famous Madison Square Garden.

Going hell for leather: Katy Perry embarked on another energetic tour show in NYC on Monday, in an array of striking ensembles

Sexy: The singer, 32, slipped her enviably leggy figure into a raunchy leather leotard and thigh-high boots, as she belted her hits at the famous Madison Square Garden

The Hot n Cold hitmaker commanded attention in the sexy one-piece, which tightly hugged her figure, and cinched in at her slim waist with a chunky belt.

She upped the sex appeal further with fishnet tights and PVC thigh-high boots – but maintained her usual quirky style with the shoes’ polka dot pattern.

Toned: The raunchy leotard cinched in at her slim waist with a chunky buckle belt

Thigh-raising! The leotard pulled into a high-neck in a bid to remain demure, but cut off at a daring height at her hip to leave almost all of her long and lean legs on show

Playful: However she maintained her usual quirky style with the shoes’ polka dot pattern as she performed for the crowd

Making the look far more elaborate, the leotard then featured a flamenco-style skirt, which cascaded down one side of her body in striking ruffles of matching polka dot.

Tying her outfit together with a dramatic disc headpiece and bright red lipstick, Katy ensured all eyes were on her as she performed a number of her hits for the crowd.

Not stopping there, she later changed into a stunning pink gown embellished with chunky jewels, and a more trendy crop top and checked trouser combo.

Speaking about the appointment in August, the I Kissed A Girl crooner admitted she was hoping to be one of the stricter members of the line-up – comparing herself to the famous British judge and Syco owner.

She told Billboard: ‘I’m going to maybe be more the Simon Cowell.

‘I really respect him. As much as people said, ‘oh, he’s grumpy or he’s mean,’ he was just truthful, you know? I don’t need to be there to win the popular race, I just need to be there to find someone I can make their dreams come true.’
