One word two meanings. Originally a blazer was "emblazoned" with club/college colours, or regimental buttons. They are loud, bright and wonderful with a boater at Henley or Lords. The navy blazer is an evolution (devolution?) of the same garment in plain blue with gold buttons. Both garments can be correctly called a blazer. The coat in the image is a sports coat.
