Christopher Bailey didn't veer far from his winning formula at Burberry Prorsum. There were the signature trenches done up this time in metallic leather velvet; the floor-scraping flares and narrow jackets with new, slightly puffed sleeves; and, taking a page from his crinkled and wrinkled Spring collection, silk matelassé cocktail numbers. Other dresses came in silk crepon printed with digitized images of a Baroque etching the designer bought at an antique shop. As always, there was a slew of luxurious fabrics, but none stood out quite like the tapestry velvet jacquard used for a three-quarter-length-sleeved sheath and an oversize caban.
