Key Trends Dominating the Season
Across the major fashion weeks, several trends have emerged, defining the style landscape for the coming seasons. Balloon trousers continue their ascent, transitioning from casual wear to luxury statements, seen on runways from Michael Kors to Ralph Lauren. The classic rugby shirt is being reinterpreted with a more polished aesthetic, offering a sophisticated take on preppy style. Transitional dressing remains a crucial theme, with designers focusing on versatile pieces that bridge the gap between seasons. In London, a return to Victorian-inspired high-neck ruffles and a strong metallic and chainmail presence were noted, alongside creative uses of fringe. NYFW also highlighted the enduring appeal of denim, with ’90s grunge influences, and a resurgence of playful accessories like pom-poms.
