Every aspect of French fashion has been scrutinised and replicated the world over, from the classic Breton striped top to Le Smoking tuxedo; from bucolic Prairie dresses favoured by Brigitte Bardot to the more rigorous bonhomie Parisian style of Loulou de la Falaise. But think back to that other Yves Saint Laurent muse, Betty Catroux, and you'll find the ultimate blueprint for relaxed utilitarian pieces mixed with classic tailoring. Her preference for Safari suits and neat coats re-showcased a pared back elegance that's stood the test of time.

Although uniform-inspired fashion will never date, its polished and practical elements are what make it a seasonal, year-round favourite. For cooler months, update the look with a focus on the ultimate colour combination of navy, tan, khaki and white - a failsafe palette so easy on the eye it will easily see you through to the spring and summer months ahead.
