While bows tend to be ultrafeminine embellishments, designers are transforming them into sleek, urban additions on the runway this week. Proenza Schouler swept a chic white bow atop a traditional silk white blouse, while Thakoon tied a printed pattern variation around Coco Rocha’s navy belted coat. Meanwhile, Marc Jacobs fastened his knot front and center for a new spin on the classic black cocktail dress at Marc by Marc Jacobs. Come fall, we’ll be fit to be tied. —Sharon Clott
