KCD president Ed Filipowski is one of the most influential—and intimidating—execs in the fashion business. As the head of public relations for KCD, he works with a wide range of prestigious clients, from Givenchy and Swarovski to Marc Jacobs and Victoria's Secret. Filipowski is also revered for nurturing—and holding onto—talent. While public relations is known for its fast turnover, the publicist—an employee at KCD since the 1980s, an owner nearly as long—has been able to keep his staff close. Currently, the average tenure for a senior-level publicist is 9.5 years. (And a KCD publicist pretty much never defects to another agency, which is also rare.) I spoke with Filipowski last week about how he got his job at KCD—and what he looks for when he's interviewing both senior publicists and interns.

Earlier this week, fashion PR powerhouse KCD announced a new partnership with London-based creative firm Spring. Spring, which was founded as a photo studio and is now billed as a "studio complex and multichannel creative agency", is run by folks with some serious fashion cred of their own: Robin Derrick, who was the creative director at Vogue UK and Armani, and Robin Harvey, who was the founding creative director of Net-a-porter. Under the Spring umbrella (divisions include Spring Creative, Spring Creative services, and soon-to-launch Spring New York) the firm develops advertising and multimedia campaigns for high profile clients like Target and Louis Vuitton. Remember that Harper's Bazaar redesign? That was them too. The idea behind the partnership is that as clients begin to have new and greater demands--for digital strategy, launching e-commerce, social media, etc--KCD wants to be able to address those needs under one roof.

Last week, fashion PR power house KCD listed a digital coordinator job on our careers page and we thought, 'Hmm...is KCD beefing up their digital side?' Indeed they are--and the ground-breaking fashion show platform they're launching might revolutionize the way fashion is seen (or at least make our lives easier). The company, who were quick to embrace digital (a rarity in the digi-phobic fashion industry), are introducing Digital Fashion Shows, a platform to deliver online-only fashion shows to buyers and members of the press, which will launch during New York Fashion Week with Prabal Gurung's inaugural lCB collection for Onward Kashiyama on Febuary 15. It's an ambitious project and offers way more than just a show livestream.
