Today is the big day.
England will play against Croatia tonight in a bid to earn their spot in the World Cup final for the first time since 1966.
And if there's one man the whole country believes can get us there, it's manager Gareth Southgate.
Southgate has become something of a fashion icon during the football tournament, making headlines for his stylish navy waistcoat, as well as leading England to successs.
Retailer Marks and Spencer, who are the official suit provider for the team, have reported sales of the now must-have fashion item have doubled in stores since the start of the World Cup, as the nation has become gripped by waistcoat fever.
Fans are now eager to get behind the manager and show their support by donning a waistcoat ahead of England's semi-final match against Croatia tonight, in what has been dubbed as 'Waistcoat Wednesday'.
