This engineer coat is a redesign of AN21's Lot.401 Engineer Coat, which is a mix of a 1940s American work coat and a 1940s British work coat. The belt is tucked and slapped on the back, but the tuck has been reconstructed to a single piece, taking into consideration the thickness of the fabric. The belt is placed at the high waist, which is symbolic of the brand. The length is somewhere between a jacket and a coat. It is made of a single layer of fabric without lining, giving it a light finish.
