After completing a mammoth 151-gig world tour, Katy Perry is preparing to wind down.

And although she’s on the home straight of her Prismatic World Tour, she’s ensuring she goes out with a bang.

Katy proved her worth and exactly how she’d managed to sell out date after date in all corners of the world when she gave a truly thrilling performance in San Juan, Puerto Rico, on Monday night.

It’s not surprising the Roar hit-maker was keen to give fans a show they’ll never forget as her previous date in Bogotá, Colombia, saw her struggle with the plus 8,000 ft altitude.

She was forced to wear an oxygen mask following her concert at Parque Deportivo 222 on Friday and shared an obligatory selfie on Twitter.

‘Singing and dancing at over 8,000 feet, no problemo Bogota, Colombia,’ she captioned the shot.

Thankfully, there were no such hindrances to her rousing show at the José Miguel Agrelot Coliseum.

A skin-tight leotard, which was rendered in purple PVC and featured semi-sheer cut-out details, provided the foundation for her stage outfits.

She proudly paraded her svelte figure in the racy number which she teamed with a pair of matching thigh-high heeled boots.

Prior to stripping off to reveal the skimpy one-piece, Katy had a gold skirt wrapped around her waist which covered her bottom.

Katy also gave the term ‘cat lady’ a much-needed sexy make-over as she sported her favourite animal-themed costume.

The Roar songstress made the most of her svelte figure as the motif one-piece was rendered in a skin-tight sheeny leather which clung to every contour.

She teamed the stand-out piece with a pair of matching lace-up thigh-high heeled boots – a metallic version of the lilac ones she stomped around in earlier on in the gig – which she had no trouble dancing in.

The chart-topper’s thighs looked especially lean in the form-fitting choice of footwear as did her upper arms thanks to the sleeveless costume.
