From classic solid colors to cut-out models. And then floral, chocolate brown, striped. The catwalks of Milan and Paris have outlined the trends that will dominate the beaches and pools, with particular attention to fine materials, sophisticated cuts and trendy colors.

The return of the one-piece to the runways and in the suitcases of the most style-conscious women is not a nostalgic revival, but an aesthetic statement calibrated to the present. After seasons dominated by micro-bikinis and minimalist silhouettes, the one-piece resurfaces with its aura of sensual, almost architectural rigor. The runways of Milan and Paris have relaunched it as an aesthetic icon, reinventing it with cut-outs , deep necklines, asymmetrical shoulder straps and couture details.

All made even more sophisticated by bold accessories such as the jewel belt with the word “Paris” and the oversized 70s glasses. A perfect mix of nostalgia and new femininity.
