Pastel hues are always popular in spring and summer, and when it comes to dressing in sorbet shades, while powdery blue and soft pinks are making their mark on the fashion colour trends of 2026, it's butter yellow that is once again set to reign supreme over the next few months.
And while this gentle hue is certainly having another trending moment, Margot Robbie's outfit from 2019 proves that this gorgeous sunshine-inspired colourway is actually a warm weather staple. Wearing a butter yellow blouse as part of a white jeans outfit, Margot not only shows that this is a colour palette that has stood the test of time, but it also works for casual and more polished occasions too.
