Frock Coat
Alongside colourful full dress costumes, plain wool fabrics in sober colours were also highly fashionable in the late 18th century. A piece of the pointed collar of this jacket was cut out at the back, and replaced with a glazed black fabric. When wearing this jacket the Amsterdam patrician Jacob Alewijn had his long, powdered hair in a ponytail. This is probably why his original collar became dirty.
