Prada, which has long been a supporter of innovative architecture and design, is the lead sponsor of this year's Ambassadors Ball—and the brand's involvement doesn't end there. The fashion label has joined forces with Alan Lo and the Dorchester Collection to curate this indulgent Milanese trip. 

Among the many highlights of the experience are a private tour of Fondazione Prada and Osservatorio, afternoon tea at the city's famous Pasticceria Marchesi and a three-night stay at the Hotel Principe di Savoia Milano, which is a favourite of Madonna, George Clooney and David Beckham. To top it all off, the lot also includes business class return flights for two.

This intriguing photograph was shot by Trevor Yeung, a rising star on Hong Kong's art scene, during a recent trip to the Blue Mountains in Australia.

It wasn't until Yeung was back in Hong Kong and developing his photos that he realised he'd absent-mindedly left the yellow filter on when he took this shot. But it was a happy accident—this moody image is sure to entice some collectors at the auction. 

Canadian artist Marcel Dzama is famous for his detailed watercolour paintings that draw inspiration from everything from Surrealist films to Soviet-era propaganda.

This work was previously exhibited in the show Art Series: Marcel Dzama - The tension around which history is built, at New York's Lincoln Center for the Performing Arts in 2016.

Hongkonger André Fu has long been a supporter of the Ambassadors of Design and Design Trust—he was co-creative director of last year's ball—and this year he's contributed to the auction.

The lot donated by Fu includes a two-night stay at Villa La Coste in Aix-en-Provence, a new hotel for which Fu designed the communal spaces, including the library, bar and restaurant. The lucky bidder will also win a Lantern Tablelamp, one of the highlights of Fu's new range of homeware.  

Thomas Heatherwick is one of the few designers in the world to have reached almost rock star-status, so there are sure to be a few fans at the Ambassadors Ball desperate to get their hands on this lot.

The lucky winner will be treated to an exclusive tour of Heatherwick's studio and one of the designer's latest projects, Coal Drops Yard in London's King's Cross development, as well as a signed Spun chair and a signed copy of the book Thomas Heatherwick: Making. As if that wasn't enough to have you reaching for the paddle, the Rosewood London has added a three-night stay to the package.

The art of Hungarian-American artist Rita Ackermann is constantly evolving—and right now it's shifting between figuration and abstraction. This oil painting perfectly captures this moment, featuring a shadowy, feminine form that seems to dissolve into the blue background.  

Need a break after the excitement of the Ambassadors Ball? This lot package includes a four-night stay, dinner for two, a wine tasting and a cooking class at the luxury hotel Capofaro on the idyllic Sicilian island of Salina.

After that, guests will be whisked in style for a three-night, all-inclusive experience at the Regaleali Estate on Sicily itself, which produces some of the region's best wines.
