I am always overly cautious when considering whether to invest in a trend or not. My rule of thumb is, Would I have bought this two years ago before it was "in" fashion? Would I wear it in two years' time after it's dropped off the social media radar? This is a thought process I went through when considering this season's patchwork denim trend, a look that, incidentally, features prominently in Whistles' latest Limited Edition collection, which launched this week.
