Wearing brights for spring/summer is a no-brainer, but if Copenhagen street style is anything to go by, stick to one hue. Whether a ruffled dress, bold co-ord, or sleek suit, the trend for next season is keeping to a single, plain colour. Teamed with neutrals to help the colour really pop, it's a look that will turn heads and make you stand out. Stick to your Barbiecore roots or branch into other colours of the rainbow to get ahead of the season.
