Nothing says timeless quite like a Breton stripe. The navy and white print is about as classic as it can get in the fashion world as it is never likely to go out of style. The nautical theme is also royally-approved, with the likes of The Duchess of Cambridge, The Duchess of Sussex and Duchess Camilla all sporting the chic pattern.
