the wait is over! The white front ruffle 'Nanette' dress is now available to buy at £159, ranging from sizes 4 to 14. The dress already appears to be causing the Reiss website some trouble, so you may have better luck popping into a Reiss store. Like the blue Issa dress which Kate wore during the announcement of her engagement, it's highly unlikely this number will be around for long so you better scoot!
