Edward Buchanan put some hustle on several levels into his debut presentation for his knitwear line Sansovino 6. He enlisted his friend Stefano Pilati to style the presentation, held at a dance hall with a live disco performance — yes, “The Hustle” included — and dancing models. Stephen Galloway coordinated. The production put a lot of charm and genuine earnest energy behind the collection, which was most un-groovy — and that’s a good thing. The look was slouchy, oversize and sophisticated in a cool librarian way. Standout looks included a gray vest over a gray sweater with ivory, roll-cuffed sleeves and baggy pants, and an oatmeal turtleneck and cardigan with one red sleeve over a maxi patchwork skirt.
