We've been glued to Michelle Obama's European tour styling over the past few days, but now Mrs O has found herself in a fashion face-off with another First Lady - our very own new Duchess of Cambridge.
Prince William and Kate were on hand to greet President Obama and his wife at Buckingham Palace, with Michelle working spring pastels in a print prom dress and bolero jacket, and Kate looking chic in a figure-hugging nude frock.
And with a world of high-end designers at her fingertips, we love that Kate chose a high street dress for the occasion. Her nude number is from Reiss, and is available to buy in stores now for just £175!
But within minutes of these pictures emerging, Middleton Mania took hold...
When we first ran this story earlier today, the nude Shona dress was available to buy on the Reiss website in every size.
But just one hour later, and not only had the style completely sold out, but the entire site had crashed due to the overwhelming number of visitors trying to access it.
Would you rush to buy the same frock as Kate? (Or, more to the point, were you one of the lucky few who managed to nab one?) We want to hear your thoughts below!
