sack coat การใช้

Both frock coats and sack coats became shorter.
In domestic settings, the sack coat or a lounge jacket could be worn with a waistcoat and trousers of the same fabric.
Frock coats were shortened to knee-length and were worn for business, while the mid-thigh length sack coat slowly displaced the frock coat for less-formal occasions.
The original uniform of the Edgefield Hussars most likely consisted of an eight-button light-colored ( probably grey ) sack coat with tape trim of lighter hue around a low standing collar.
The blazer, a navy blue or brightly colored or striped flannel coat cut like a sack coat with patch pockets and brass buttons, was worn for sports, sailing, and other casual activities.
