Amongst the artefacts in Gucci's new museum, the most eye-catching attraction was undoubtedly Prince Albert's niece, Charlotte Casiraghi.
The iconic brand has gathered vintage handbags, gowns and even a surfboard by Tom Ford from its archives to mark 90 years in the business.
And visitors will also be able to marvel at a 1979 white Cadillac Seville featuring the famous double G logo.
At the glittering inaugural party, the guest list was headed by the pretty royal.
Exuding her late grandmother's signature elegance, Charlotte mingled with VIPs like US Vogue editor Anna Wintour and Debbie Harry.
Her silky jade green fringed frock was a show-stopper.
But the fashionable aristocrat toned down the bright outfit with a ponytail and simple black, t-bar stilettos.
She maintains good relations with the Italian brand – they designed the equestrian attire she wears to compete.
