In pictures: The six top trends from London Fashion Week

Stripes (Preen by Thornton Bregazzi): The absolute opposite of the florals and jewelled embellishments that have been popular for so long, the stripe felt fresh and no-nonsense, whether as a mere highlight on a pocket at Jasper Conran or in giant crocheted bands at Sibling. Preen, though, based its whole collection on many iterations of the stripe, from flowing navy, white and red layers perfect for St Tropez lounging, to waistband and neckline accents adding a graphic edge to flowing romantic prints, and finally deconstructed stripes chopped into fringing and appliquéd to a little black dress.

White (Sibling): After seasons of complex prints, fussy, over-thought styling and complicated tailoring, it felt like the slate was being wiped clean at London Fashion Week, and no trend encapsulated this more than the gleaming white outfits that were seen on catwalks from the stylish veteran Amanda Wakeley to the young rule-breakers Sibling. And without colour, the focus was very much on the fabrics: white silks looked serene and ethereal, white linen fresh and Riviera-ready, and white canvas or cotton seemed almost utilitarian and oh-so pristine. The easiest ways to wear it included silken tunics, crisp tailoring and relaxed cropped pants. Tim P Whitby / Getty Images

Midi skirts (Emilia Wickstead): The full skirts that have accompanied the Mad Men obsession for some seasons have grown up for next spring: they are longer, less frothy and deeply flattering. The always-romantic Marchesa, which celebrated 10 years in the business this season, showed skirts swishing around the calf, both appliquéd in organza and printed in satin, while the otherwise minimalist Barbara Casasola included metallic midi skirts given body with sunray pleats. Emilia Wickstead, though, took the look to its natural conclusion with a rich orange, heavily textured dress that scraped the ankles, a modern take on her signature 1950s-tinged style.

Diagonals (David Koma): With pattern very much taking a back seat and tailoring simplified, it took a little extra effort to dress the body flatteringly, but there’s nothing like a diagonal line to add dynamic movement to an outfit, slenderise a torso and add a certain sense of caution-to-the-wind fashion savvy. Preen by Thornton Bregazzi, Marios Schwab and Lucas Nascimento all made use of the optical illusion offered by this trend, but it was in the young Brit David Koma’s collection that it was particularly striking. Previously known for his intricate, perfectly symmetrical frocks in the vein of Alexander McQueen, Koma took to diagonal prints and cuts with gusto, in clean monochrome dresses, tops and skirts sliced and wrapped to zig-zag across the body.

Cropped trousers (Temperley): Hardly a full-length pair of trousers was to be seen in London: summer suits were paired with shorts, culottes and, most commonly of all, casually turned-up, loosely tapered trousers. One thing is for sure: skinny is out and wide, flapping pants are in. Amanda Wakeley set the tone with her relaxed tailoring and Temperley London picked up where she left off, with laid-back checked trousers teamed with plimsolls and long, loose, silky coats. They ranged from wide calf-length palazzo-style trousers with matching waistcoats and tux jackets in creamy crepe to super-casual rolled-up pyjama pants. Carl Court / AFP

London Fashion Week is better known for its unfettered creativity than for solid trends that will go all the way to the high street, but for the spring/summer 2015 collections, which have been on show this week, the city has grown up. Deliciously wearable for ordinary women everywhere, the pieces we will be wearing next spring are all about classic style, flattering detail and simple, fuss-free ensembles. From a white-and-blue Mediterranean palette to the latest way to wear the trousers and swooshy, romantic skirts, here are the six top trends to take you through to the next season.
