Katy Perry certainly knows how to put on a performance.

Hosting last night’s MTV EMA’s the singer made the event her own by showcasing a spectrum of crazy fashion finds.

Pictured in an alarming Viktor & Rolf Spring 2009 ball gown, Katy opted for shock tactics on the stage.

The strangely shaved netting and bullet-hole-style cavity is a bit too eerie for such a light-hearted event.

I loved the dramatics in Viktor & Rolf’s Spring presentation, however this dress screams ‘DANGER!’ Sorry Katy, car-crash couture.

This is more like it.

Sampling a Marchesa 2010 dress, Katy looks like something from a vamped-up version of a swan-lake production.

Feathers seem to be a favourite with Marchesa for Spring 2010.

Here they complement the lace body, adding movement and texture and give Katy the extra detail that she needs. This dress has already been worn by Camilla Belle.

I love the white on Katy. It’s clean, fresh and works with her dark hair and eyes radiantly.

This Georges Chakra Couture Fall 2009 gown has hints of both pin-up glamour and a 1930′s flapper dress.

Katy is captivating here, the sparkling blue sequins and pearls on the dress turn Katy from a loopy pop-star into a siren.

Showing off her figure, and quite rightly too, Katy sticks with a more mature look.

Katy wore a second look by Georges Chakra, this time from his Spring 2010 ready to wear Edition collection.

The Lebanese designer dedicates his work to a modern, self-confident woman, making Katy a worthy fit for his designs.

This dress is another of Katy’s more ‘wacky’ choices. Having modified the hem to make a structured skirt, it resembles the carousel dress that the singer wore at last years EMA’s.

Ultimately wearing this dress whilst swinging on a decorated seat doesn’t really do much for the singer except confirm what we already knew; slightly bonkers.
