Decor becomes dress thanks to the creative minds of London fashion designer Erdem Moralioglu and French design house de Gournay. Heralded for its handpainted chinoiserie wallpapers and fabrics, de Gournay is no stranger to fashionable fraternization—past bedfellows read like a who’s who of the style clique: Aquazzura, Jeffrey Bilhuber, Kate Moss.

Its collection with Erdem includes wallcoverings in chic shades, such as Golden Yellow, Adam Grey and Kelly green, and offers a vibrant burst of florals as hydrangeas, hollyhocks, irises, chrysanthemums and morning glories creep across branches dotted with sparrows, warblers, pheasants and egrets. Complementary navy and white dresses in elegant silhouettes echo the birds, branches and fields of flowers. The result is a halcyon homage that blooms anew.
