Fact fans, did you know that the original Breton top was created as part of the uniform for all French navy seaman in Brittany - and that it had to feature 21 stripes, one for each of Napoleon's victories?
Well, if you didn't, don't worry too much; Coco Chanel was the one who really brought the Breton top into the fashion world (who else could it have been?).
The iconic designer introduced the classic French style into her nautical collection in 1917, which moved the look from working class to high fashion.
Since then the popularity of the striped top has remained strong and it never looks out of place in a spring and summer wardrobe - you need only glimpse pictures of Marilyn Monroe, Audrey Hepburn and Kate Middleton to see that it's a style staple.
