Amazon is finding women’s fashion, a missing piece of its household-centric model, a tougher nut to crack than downmarket apparel.

Higher-end US department stores are pushing back with an omnichannel model, emphasising long-term partnerships, a clever full-price/outlet model, and experiences which cross the online-offline divide.
