The supermarket said it sold a quarter of a million of the women's work outfits last week, selling one every 30 seconds in the first 24 hours after it launched.
George hopes its men's promotion will follow suit this week and has 160,000 shirts to cover demand. The supermarket found in a study of 1,000 men that a shirt is a major part of a man’s wardrobe, with 74% of men choosing to wear a shirt to work and during their own leisure time.
The men’s shirts are available in both long and short sleeves, in classic white or blue. They normally sell for £3 each.
Brand director Fiona Lambert said: "George customers like great style at a great price, with our latest offer guys can buy two shirts for less than a coffee and a croissant, or a sandwich and a soft drink."
