London can always be relied on to provide the more leftfield side of trends. Slapped in the middle of New York and Milan, the cities where playing it safe and a heavy dose of commercialism reign high, London is always there with the trends that perhaps won't necessarily sell well, but are fun and frivoulous, lightening the international fashion week trawl up a notch or two. Crazy Lace, acid bright colourways and Good and Bad taste all featured in the week of Leftfield London. That said, trends that are key and will sell for next season also made an appearance on the British catwalks. Burberry stands out once again with the key jacket shape of the season. With the popularity of their Autumn/Winter shearling Aviator blouson, Christopher Bailey moves on to an edgier version for spring, which comes in the form of cropped motorcycle jacket taking its styling cue from the brand's classic trench coat. Acne also included a shoulder studded biker jacket in their spring /summer presentation. At Erdem and Michael Van Der Ham, peasant patchworking was a key fabric of the season. Erdem's floral triangle-cut prints served to create a beautiful full skirted fifties style prom dress and Van Der Ham played with cutting and pasting random garment parts to form colour blocked dresses. After a winter season of dainty kitten heels, London designers have decided that for spring our feet will be back in patforms, although the newness next season will come in the form of oversized wood block wedges with 'Geisha' style leather toe-thongs and ankle ties.
