Giles Deacon continued to play on the ladylike silhouettes that have become his calling card over the past few seasons. “It’s that overall haughtiness that I quite like,” said Deacon. The collection spotlighted polished pieces such as a cropped wool crepe jacket in moss green, a sleek black tuxedo suit and structured yet voluminous coats with sweet round collars, in pale pink or rich brown duchess satin. But the lineup was still spiked with Deacon’s signature sense of fun. Jackets had punkish metal studs for buttons, while the stud motif was also done in an intarsia design on a wool sweater. And a series of cute fashion illustrations — which Deacon doodled using an app on his iPad — adorned silk pajama pantsuits and draped silk shift dresses.
