EXCLUSIVE AT NET-A-PORTER.COM. We love how Ronald van der Kemp uses couture-like construction in a modern, feminine way. Crafted in the designer's native Holland and sewn with intricate French seams, this white cotton-batiste blouse has a soft and slightly sheer finish. The ruffled collar and cuffs are complemented by long draped ties. Vintage and antique pearl buttons complete the elegant picture.
