What's not to love about London Fashion Week? Unconventional designers, quirky models and daring ensembles – both on and off the runways – make every London Fashion Week a little bit different than those other fashion weeks in New York, Paris and Milan.

The iconic Mrs. B, Joan Burstein of Browns, still remembers the magic of early London Fashion Weeks: "The early days of John Galliano were just breathtaking. I also loved Jean Muir, who everyone seems to have forgotten about. But they just keep getting more and more wonderful each year."

This year, London Fashion Week celebrates its 25th Anniversary and is pulling out all the stops, including a new venue on the Strand, top front-row fixtures like Anna Wintour and Kate Moss and luring prodigal British designers back home.

Christopher Bailey has brought the iconic Burberry label back to its roots on the London catwalk, while other designers who have gone back and forth across the pond like Matthew Williamson and Jonathan Saunders are showing here again this season.

London has long been known as a bastion of creativity, the breeding ground for fashion's eccentrics, enfants terribles like John Galliano and Alexander McQueen, who are now two of the biggest names on the international fashion scene.

The great Vivienne Westwood has brought us everything from punk to pirates to Carrie Bradshaw's wedding dress, all the while campaigning for her favourite global causes.

While designers like Christopher Kane, Giles Deacon, Luella and Gareth Pugh have already left their imprint on fashion, new blood like William Tempest, Peter Pilotto, Aminaka Wilmont and Mark Fast (who pushed boundaries with his plus-sized models this season) are gearing up in the wings, ready to dictate what we'll be wearing in seasons to come.

Meanwhile, London Fashion Week has seen some of the world's most famous faces on its catwalks, from Victoria Beckham to Naomi Campbell, who opened Issa's show this season.

The modern-day British It girl crowd of Pixie Geldof, Daisy Lowe, Alice Dellal and Alexa Chung continue to rock the runways of their favourite designers like PPQ and Pam Hogg, actively involved in London fashion's future. "London is great because there is a great energy towards new fashion," says designer Maria Francesca Pepe.

"In the next 25 years, I am curious to see how fashion will evolve and would like London to be the place to be for originality. Fashion can go in so many directions and London is a testimony of that."

London Fashion Week has been more than just models walking up and down a catwalk, according to Fashion Fringe founder and Times columnist Colin McDowell. "What really sticks in my memory are the marvellous Alexander McQueen shows, like the one with all of the birds," he says. "It was theatre as world fashion. That's what London is all about."

Fashion here is constantly evolving and always exciting, and you never really know what – or who – to expect. And that's what we love most about it.

Happy anniversary, London Fashion Week!
