Lady Gaga Phillip Treacy

Lady Gaga watches on at Phillip Treacy's London Fashion Week show. Her floral number had some tough competition on the runway - here, a walking light fitting.

London Fashion Week has always been known for its irreverent take on fashion, blurring the lines between intimidating edginess and borderline-daft insouciance.

Given all that, we're still not sure that Lady Gaga gets away with this look: enter, the floral helmet.

The pop star looked remarkably relaxed wearing something that defies technical terms - its closest relation is perhaps a bonnet - to the Phillip Treacy show in London on Sunday.

Did poor Gaga get her head stuck in a floral wreath - a victim of the little-known dangers of smelling the roses? 

Or perhaps it is an elephantine floral bath cap - a new soap-sud driven trend that those sitting behind the front-row maven may have pondered as the spring-summer collections on the catwalk were utterly obscured from view.

While the bouquet-crossed-with-a-human-cannonball look may be great for promoting cross-pollination, we see little real practicality here, wardrobe wise. And the same goes for a full-length twinkling number that was reminsicent of a walking light fitting. We sense, however, that that is not the point.

It beats a hat made of raw meat: Lady Gaga's headdress was certainly eye-catching.

Whatever it is - and milliner-to-the-stars Treacy is responsible - it puts Carmen Miranda's fruit basket headdresses to shame. The entire show was a visual delight, heavy on spectacle and light on functionality. This, we must remember, comes from the man who created Princess Beatrice's infamous and globally-panned pretzel hat.

Brilliantly mad, other-worldly and in every sense escapist, the spring/summer 2013 collection has been met with rave reviews after a 13-year fashion week hiatus for the London-based label.

Not content to simply steal the limelight with her hat, Gaga also acted as a master of ceremonies at the show, wearing a neon pink veil and towering Alexander McQueen Armadillo shoes - not that her turn on on the runway prompted much exclamation given the scale of the visual feast.

Lady Gaga acted as MC for Phillip Treacy, donning a neon veil and sky-high McQueen heels to do so.

There is one thing we can hand to the newly shaved-headed songstress: the bloom-laden diving bell is the perfect look for camouflaging a bad hair day.

Oh, and for attracting attention, of course.

And, as much as we can imagine the collective eyeball-rolling prompted by her latest artistic guise, its silliness beats a hat made of raw meat, any day.
