Within minutes the chic Shola taupe creation sold out on the brand’s website, with fashion fans crashing the online store, all clamoring to get their hands on the high street item.
But brand officials have blamed 'unprecedented traffic' for the event, and promised to get the site up and running – and Kate’s dress back in stock – as quickly as possible.
'Due to unprecedented demand, Shola mania has crashed our website!’ a Reiss spokesman Tweeted yesterday. ‘We are endeavouring to bring the Reiss brand back to you ASAP!'’
The second time the Duchess of Cambridge has chosen the brand for a high profile appearance - she wore a white dress for her official engagement photo shoot with Mario Testino - it's the latest in a string of affordable fashion buys to be spotted in her wardrobe, including pieces from LK Bennett and Whistles.
