A dress costing £230,000, embellished with more than 150,000 Swarovski crystals, will go on display at Harrods this week as part of its Crystal Christmas event.

The Ralph & Russo-designed dress will be the centrepiece of the department store’s Swarovski-sponsored window displays over the festive season.

The dress, inspired by the decadence of the Twenties, took more than 25 people working on it and is the result of hundreds of hours of man hours.

Harrods is housing a Chanel takeover. Until September 24th, two pop-up boutiques, the Brompton Road windows and an outstanding installation, will all pay homage to the iconic French brand.

The Brompton road store façade features themed windows, inspired by Lagerfeld’s most recent whimsical Ready-to-Wear collection, with a magical forest theme.

Situated on the Third Floor, the installation encompasses eight rooms dedicated to milestones in Chanel’s history.

Swiss watchmaker Tissot has partnered with Holition to showcase its Ladies and T-Touch collection in one of Harrods iconic Brompton Road window displays as part of the store’s new promotion celebrating all things Swiss.

The augmented reality application will be live and fully interactive on weekends between 12pm and 6pm from 1st – 24th April.

The window display will enable consumers to virtually ‘try on’ watches from both the Ladies and T-Touch men’s collection, and a fully interactive touch screen will allow customers to engage with a wider range of Tissot watches than ever before.

Designers Studio XAG have created a window installation in London for fashion designer Christian Louboutin, spelling out the brand name in bright neon lettering.

The window is furnished with a neon arrow and an array of backlit oversized perspex letters decorated with bulbs.

A white Lexus CT 200h will be spending the Holiday season in the window of Harrods of London, the UK’s most famous luxury store.

The CT 200h will be unmissable as shoppers along London’s Brompton Road take a break from the usual Christmas window displays to see the car in full view.

The presentation has been designed so that people can access the new full hybrid luxury hatchback, plus its sister RX 450h SUV model that is also on show.

Aston Martin’s new luxury city car Cygnet is making its global debut at Harrods in Knightsbridge, the world’s most prestigious department store.

The Toyota iQ-based Cygnet will go into production in 2011 at the company’s global headquarters in Gaydon and is expected to cost from £30,000.

Cygnet will be available to view at Harrods until Saturday 18th December with the car on sale now through Aston Martin’s European dealership network.
