The most stylish individuals I know are already sporting the trendiest color pairing of autumn.

      I can easily identify a fashion enthusiast from a distance, and currently, one of the most apparent signs that someone is well-versed in style is whether they are trying out the bold colour combinations that are poised to trend next. Notably, Katie Holmes caught my attention as she stepped out in New York wearing the exact pairing that the runways have already highlighted as one of the most exciting looks for autumn 2026. At an event in the city, Holmes traded the classic black-and-white for a royal purple dress, accentuating her outfit with a pair of ruby-red shoes.

      The color combination is already gaining traction on the runways, with Miu Miu, Prada, and Celine all advocating for the pairing of striking hues. Instead of clashing, royal purple and ruby red complement each other, creating a vibrant duo that feels entirely new for autumn. Inspired by Katie, continue reading to discover the colour combination that I believe will soon be a staple for many—and check out the trend below.
