Two quintessentially British brands, Alice Temperley and John Lewis, have joined forces to create new label Somerset by Alice Temperley, launching this September. The label takes its name from Temperley's beloved home county and is the first collection the designer has produced for the UK high street. Collection highlights include pretty Victoriana lace dresses, floppy hats, chic wide-legged trousers and silky evening dresses (rightly so, lest we forget it was Temperley that Pippa Middleton wore to that wedding after-party). Suitable for swanning around chocolate box villages, packing for country escapes, or for celebrating with royalty - Somerset by Alice Temperley is available from John Lewis stores and online, with prices starting at £29. johnlewis.com

"She was wonderful! She was fun, interesting, generous, supportive. Just a wonderful grandmother," says Alexander Vreeland of his granny, Diana, who changed the course of fashion throughout her legendary career. The 20th century's most prolific arbiter of style is the subject of The Eye Must Travel, a documentary released this month, and the inspiration behind a new 18-piece jewellery collection by Atelier Swarovski. "My grandmother loved to wear oversized costume jewellery. She loved the scale and colour and you can see that in how she dressed and in how she styled her shoots for [American] Harper's Bazaar in the '40s and '50s, and as editor-in-chief of American Vogue in the '60s," says Vreeland. "The jewellery is really an homage to her; it's inspired by the pieces she had and the proportions she believed in. The collection is true to what she did [with her styling for Harpers Bazaar and in her own wardrobe] but it's not at all dated." The collection is every bit as dramatic as the editrice herself, with a standout gilet made from black pearls, chains and crystals; and cuffs, bracelets and earrings that echo military crosses. The Diana Vreeland Legacy Collection is available at atelierswarovski.com

This September, Burberry will open the doors on its all-singing, all-dancing shiny new store on Regent Street. It will be the biggest Burberry store in the world, on the site that was recently occupied by Habitat. Built in 1820 for the Prince Regent, the space has been home to livery stables, galleries, a tea room, cinema and radio broadcaster, a gentleman's outfitter and a restaurant, but now it will be where the Burberry world comes to life through state-of-the-art technology that will see the brand's physical and digital spheres collide. There will be a 6.9-metre high screen (the tallest retail screen in the world), iPads everywhere to access burberry.com, 420 speakers to accommodate live music performances, its own satellite for digital streaming of shows and events, and a digital gallery with images from Burberry's Art of the Trench social media platform.

This will be a store on steroids, with in-store playlists designed by Christopher Bailey featuring Burberry Acoustic artists, a concierge, an alteration and out-of-hours collection service, an events program to showcase the best emerging and established talents in art, music and cinema, and a hydraulic stage to host live performances. Impressive, no? All Burberry products will be available here - from ready-to-wear, bespoke and childrenswear, to eyewear, watches and beauty - and there will also be an exclusive limited edition collection of trenches, shoes and bags to celebrate the new shop, which has been put together by a crack team of British master craftsmen and artisans. burberry.com
