• A stunning wedding dress worn by Diana, the Princess of Wales – including its 25 foot long sequin encrusted train – and a rare surviving ‘toile’ – a working pattern – of the 1937 coronation gown of Queen Elizabeth, The Queen Mother, are among star items on display in a new exhibition in Kensington Palace’s Orangery. Royal Style in the Making features some never-before-seen items from the archives of some of the most celebrated royal couturiers of the 20th century as well as original sketches, fabric swatches and unseen photographs from the Royal Ceremonial Dress Collection, a treasure trove of more than 10,000 items of dress and design history cared for by Historic Royal Palaces. Admission charge applies. The display can be seen until 2nd January. For more, see www.hrp.org.uk.

• The first in a series of ‘blossom gardens’ has been opened by the National Trust in Queen Elizabeth Olympic Park in London’s east. The garden features 33 trees including cherry, plum, hawthorn and crab apple which represent the city’s 32 boroughs and the City of London itself. The garden, which was opened last month by the Mayor of London, Sadiq Khan, will be followed by further gardens planted over the next five years across England, Wales and Northern Ireland.

• The brightest colours ever created are dazzling eyes at Kew Gardens. Naturally Brilliant Colour, an exhibition in the Shirley Sherwood Gallery of Botanical Art, explores the origins of colour and vision and showcases how botanical artists have depicted the brightest and most intense colours found in nature. Works by Robert John Thornton (1768-1837) and contemporary artist Julia Trickey are on show as well as the world’s first botanical artwork to accurately reproduce natural structural colour (it features flakes of ‘Pure Structural Colour’ which artificially replicates how microscopic structures within the surface layers of plants and animals reflect sunlight in a specific way to generate bright colours). Runs until 26th September. Admission charge applies. For more, see www.kew.org.
