I can spot a fashion person a mile off, and right now, one of the clearest tells that someone knows their Prada from their Proenza is whether they’re already experimenting with the high-octane colour combination set to take off next. Naturally, Katie Holmes was one of the first to catch my eye, stepping out in New York in the exact pairing that the runways have already singled out as one of autumn 2026’s most exciting.

Attending an event in the city, Holmes swapped the tried-and-tested black-and-white combination for a royal purple dress, punctuating the look with a pair of ruby-red shoes.

The colour pairing has already made its mark on the runways, with Miu Miu, Prada and Celine all making a case for putting high-impact hues side by side. Rather than competing, royal purple and ruby red build on each other to create a dynamic combination that feels entirly fresh for autumn.
