When it comes to the Fashion Week calendar, London is undoubtedly the most experimental of the capitals, while New York is commercial, Milan is all about glamour and Paris showcases high-end chic.

That means that the trends observed in London are often the most innovative and fresh, and this season was no exception.

Fashion-goers from around the globe flocked to the catwalks over five days to soak up spring/summer 2015. You may not even have bought your winter coat yet, but these are the looks set to steer the high street early next year.

Take notes, and if you want to be really fashion-forward, jump on your favourite trends now. Say hello to next spring's style...

THE COLOUR: GET THE BLUES

The coolest way to wear colour on the catwalk is head-to-toe in one tone. While white was hot on the agenda at Joseph, Temperley London and Pringle of Scotland, real colour came in various hues of blues.

"It was a relief to see colour begin to soak through in the cyans, cornflowers and cerulean blues at Christopher Kane, Jonathan Saunders and Matthew Williamson," says Katie Smith, senior retail analyst at EDITD.

THE TEXTURE: DARK DENIM

When it comes to trend-setting shows, Burberry rules the runway. The uber-brand, famed for its trench coats, opened this season's The Birds and The Bees collection with an indigo denim jacket.

"There were fitted denim jackets, some trimmed in marabou, alongside giant paillettes, sneakers and bowling bags - all of which spoke to the Nineties theme," Smith says.

The new It staple was mixed with high-octane glamour - work your denim jacket with a sequin skirt or tulle bow to be a Burberry girl.

THE THEME: SPORTS DAY

Don't pack away your posh gym kit just yet; designers unveiled plenty of sports-inspired luxe details from their lockers.

Smith says: "There were bomber jackets at Antonio Berardi and tube socks and sheer panelled sweaters at Joseph.

"The best new direction for this casualwear came in Nineties interpretations; the stripe-trimmed sweaters, cami dresses and flippy skirts of Topshop's party girls, and sheer layers, bias cuts and spaghetti straps at Richard Nicoll."

THE DECADE: FLOWER POWER

Every year, retro references infiltrate the catwalks, and this season it was a Woodstock-worthy late Sixties/early Seventies vibe.

Travel through the style time machine with kick flares, platform shoes and bright crochet.

"New York decisively picked the Seventies as its most referenced decade," Smith reveals. "Matthew Williamson, House of Holland, Tom Ford and Peter Pilotto gave the Seventies a turn with glam rock, psychedelic florals and disco references."

WEAR THE TREND NOW: Topshop Crochet Patch Top, £40 (www.topshop.com).

THE FIT: LET LOOSE

Give bodycon the brush-off; fluid fabrics are big for spring/summer 15, in the form of uber wide-legged trousers and swinging culottes.

"Legwear is set to expand for SS15," Smith predicts. "The strongest pieces were at Jonathan Saunders [scrunched and bow-waisted], Temperley London [swinging culottes], Paul Smith [loose-fit city shorts] and Matthew Williamson [high-waist flares]."

WEAR THE TREND NOW: Whistles Hoshiko Patchwork Culottes, £195 (www.whistles.com).

THE PRINT: LINEAR MODE

Graphic stripes are go for next season, whether it's laidback pyjama style or hypnotic mixed stripes.

"Designers haven't shied away from all-over stripe looks," Smith says. "Giles' striped pyjama suit was accompanied with matching footwear, Preen went crazy for cricket stripes, and Peter Pilotto offered asymmetric panels on skater dresses, carrying varying stripes to good effect."

WEAR THE TREND NOW: Karen Millen Stripe Shift Dress, £160 (www.karenmillen.com).

THE SURFACE: HIGH SHINE

Metallics move forward every season with new textures. For spring/summer 15, glitz finishes came in the form of patent leathers, high-shine plastics and lurex fabrics.

Smith says: "The electric sheen of metallic fabrics was seen on numerous catwalks around the capital, in disco form at Tom Ford, space age party dresses at Markus Lupfer, and carrying the Nineties/Millennial theme home at Richard Nicoll.
