Three Quarter Length
Three quarter length or mid calf length is a coat that covers 3/4 of the garment worn beneath it.
Seven Eights Length
Seven eighths length or knee length is a coat that conceals 7/8 of the garment worn beneath.
The most versatile style in a fur is a full-length coat because it goes with everything from pants to skirts to formal wear.
Greatcoat is an ultra long, full-length coat, loosely cut sometimes even grazing the ankle. This is the most formal of all styles, perfect for evening wear.
