French swimwear brands and Marilyn Monroe‑inspired styles lead 2026 summer fashion

French designers are shaping the 2026 summer swimwear market with a focus on refined cuts, creative prints and sustainable materials. Brands such as Banana Moon, Eres, Sézane, Albertine, Nénés Paris and Chantelle highlight recycled fabrics, traceability and resistance to chlorine or salt, while noting that French design does not always mean full‑time French production.

At the same time, designers Julien Dossena for Rabanne and Chemena Kamali for Chloé are reviving 1950s swimwear, celebrating Marilyn Monroe’s centenary. Their spring‑summer collections echo five iconic Monroe pieces – a classic black one‑piece, a gold lamé suit, polka‑dot prints, a crisp white one‑piece and a timeless black two‑piece – aligning vintage aesthetics with contemporary fashion.

Together, the French brand emphasis on sustainability and the retro‑inspired runway looks illustrate how heritage and nostalgia are driving this season’s beachwear trends.
