Okay so I get it that different jacket styles have their own ideal cuff lengths. Some look better with shorter sleeves, some better with longer sleeves. But as far as winter garments, biker and military jackets go, what is the ideal sleeve length? Do you like it to tend right where your wrist meets your hand? Or do you prefer the middle between the 1st thumb knuckle and the wrist? Or an inch above the thumb knuckle? And inch below the wrist? Is there even a fashion rule of thumb to this?
