At the Waldorf Hotel, Paul Costelloe transported his audience to a cinematic 1960s Beverly Hills with Boulevard of Dreams, his Spring/Summer 2026 collection. A designer revered for dressing Diana, Princess of Wales, in the 1980s, Costelloe balanced his hallmark tailored elegance with a lighter, more playful vision of glamour that felt both nostalgic and freshly relevant.

Rather than indulging in mere retro pastiche, Costelloe reinterpreted the golden California spirit of Rodeo Drive through a contemporary lens. The opening looks—baby blue trapeze minis, butter-yellow twinsets, and sherbet-orange cut-out dresses—set the stage like a Slim Aarons photograph come to life: palm-lined boulevards, pastel convertibles, and effortless optimism.

Color played the starring role. Tangerine, turquoise, coral, and lemon yellow were deployed with precision, anchored by pearly highlights that softened the edges and prevented costume excess. The silhouettes, meanwhile, honored the 1960s but carried a modern sharpness: trapeze dresses and drop-waist shifts refreshed with cut-outs, oversized bows, and cropped proportions. Lightweight tweeds became breezy swing coats and cocktail suits, styled with matching pastel platforms and structured handbags for polished, head-to-toe statements. Bouffant hair completed the vision, channeling Beverly Hills socialites more than London cool girls, perfectly reinforcing the story of cinematic glamour.

While the collection dazzled visually, its reliance on complete, full-look ensembles sometimes undercut versatility. Many outfits read as styled moments rather than adaptable separates, a challenge for consumers seeking flexibility in their wardrobes. Still, for what Boulevard of Dreams may have sacrificed in practicality, it made up for in atmosphere, cohesion, and sheer joy.

With this collection, Costelloe reminded us that glamour is not a costume but a state of being playful, precise, and unapologetically visible. As fashion leans into pragmatism, Boulevard of Dreams insists that summer 2026 will be luminous, bold, and impossible to ignore.
