Emma Fletcher had a practical focus this season: to hone the best-selling pieces women know and love from the brand. (Fall also marked the start of a lower price point for the label, which will now range from $200 to $400, with coats topping out at $600.) That meant plenty of silk dresses and classically feminine separates, which Fletcher deftly balanced with sexy leather miniskirts and boyish, oversize coats. She drew inspiration from a poem written by William Roscoe in 1802, “The Butterfly’s Ball and the Grasshopper’s Feast,” in particular the trippy, psychedelic illustrations that accompany the piece in a children’s book, which is popular in Fletcher’s native Australia. That explained a whimsical mushroom-and floral-print black dress, while other looks came with polka dots, ruffles and lace accents.
