Just in time for winter, up-and-coming designer Alberta Bucciarelli has created a puffer like no other.

In what is believed to be a world-first, the 21-year-old knitwear designer has created a machine-knitted puffer jacket using expandable yarn, so the garment's warm filling is manufactured at the same time as its outer layers.
