Stephanie Danan and Justin Kern infused their pre-fall lineup with a “Days of Heaven” sense of romance on the prairie, updated for 2017. There was quite a range, from black floral embroidered dresses and knits with pearl embellishment to lightweight white eyelet and true blue denim. For pre-fall, Danan and Kern also introduced an essentials group, a year-round offering of core pieces — knits, blouses and dresses — with a proven track record.
