In Scotland you will find that age determines the style to a large extent. Anyone under about 40 years is likely to wear chunky boots, scrunched down hose/socks and a casual top/sweater. Old farts (like me) are more likely to wear standard brogues, hose pulled up and either a shirt & tie with a tweed jacket or a chunky sweater. In all cases, young and old, a tartan kilt will be worn.
