Every year, as part of the Bread & Butter Show in Berlin, Mustang invites to an exclusive "Dinner for Friends". This year's invitation had to be personally addressed to the 25 guests and leave a lasting impression. So we sent out the first portable book. Page by page and seam by seam, a continuous thread leads through the success story of Mustang. At the end of the book was the invitation and when the thread was loosened, the perfect outfit opened for the party.
