Amal Clooney was the first- she attended the Royal wedding of Prince Harryand Meghan Markle in a chic marigold yellow dress. A couple of weeks later it was Meghan herself who wore a canary-yellow sheath dress to an official engagement. And then came Kate Middleton, who donned a lemon yellow outfit to attend Wimbledon final match. So, it's official: Yellow is the colour of the moment. And not just to be used in casual outing or holidays activities. It can be worn at ceremonies or more formal occasions. Choose among the mini, midi or maxi dresses created by Asos, the stunning Versace style, and the minimal chic dresses by Valentino.
