Kate Spade may have uptown prices, but the brand's always managed to cling to their cool, thanks to stores based only in Soho, ingeniously sharp ad campaigns, and nifty artist collaborations. But now that Kate Spade herself has left the line, things might be shifting into soccer mom territory. Liz Claiborne, the brand's mother company, is opening a new Kate boutique... on Fifth Avenue and 20th st. The imminent store neighbors H&M, Armani Exchange, J. Crew, the Gap, and - most tellingly - Coach, on one of the most tourist-trafficked streets of Manhattan. Is this an indication of Kate Spade's future? We think so - Liz Claiborne is out for big business, remember. But if Kate loses her cool, will her brand following drop?
