Bottega Veneta BV 25FW Knitted Sheepskin Collar JacketTo be honest, this collar is really quite challenging to make. Each horizontal strip is hand-woven by professional workers, and all the horizontal and vertical parts must be aligned precisely. Moreover, the corner treatment of the navy blue version is quite complicated, with all the edges trimmed to the border line. The triangular pocket for measuring the chest circumference is also included.
