Everlane isn't like many other contemporary fashion brands. While others drive profits by discretely marking up low-cost goods, Everlane discloses the line-by-line costs for producing their products - and how much money they make on each transaction. While others obscure details about their supply chain, Everlane devotes a whole section of their website to photos and information about their factories. How'd the company build such a transparent and nimble brand?
