There are a number of factors that led us to the conclusion that the yellow dress is set to be the dress of the summer. First, of course, is Emma Stone's Iconic frock in La La Land. Then, there's the fact that yellow is Generation Z's colour (sorry, millennials, but pink is about to be usurped). During fashion week, we saw the hue everywhere, particularly in the form of one Tibi dress (pictured below) on numerous street stylers. Finally, we spotted a load of yellow dresses from other designers and the high street.
