How does a fashion designer go from moodboard to designs?

In his debut pre-fall ’17 collection Francesco Risso the Marni creative director explained, “I was thinking about mystery boxes,” and “I imagined every outfit as being a warm cocoon that opens up to reveal a dense, intricate inside,”. He said, “I was inspired by the classic codes of bourgeois clothing, robust on the outside but precious and intricate on the inside. The coats are something to wrap up in, but they reveal colourful lining”. “I wanted to convey a sense of shock. A vertigo, a visual delirium,” Risso explains. Take a look at his #moodboard for this collection (on Vogue) and you can see bold colours and then next to this you will see some looks from this collection.
