Kate, 30, looked stunning in the long-sleeved version, which emphasised her slim waist, and - despite the £1,200 price tag - it sold out in minutes.
We love the scoop neck and the longer length on Kate, which gives the frock real elegance.
Now you can get Kate's look from Celeb Boutique who have a very similar frock for just £119.99, a tenth of the price.
Lizzie Red Long Sleeve Pleated Dress, available in XS, S, M & L
