TYPICALLY, NICOLAS DI FELICE, the 42-year-old Belgian designer of the French fashion house Courrèges, wakes up around 7 a.m. This morning, on what feels like the first Monday of spring in Paris’s 19th Arrondissement, his alarm went off earlier, an hour or so before dawn. It’s two days until the brand’s fall 2026 runway show and he wanted to get in a head-clearing walk with his Dutch-born partner and close collaborator, Roderick Buijs, 35, Courrèges’ head of creative.
