Mrs. O! Kate Middleton! Together! In the same room!

The Duke and Duchess of Cambridge are back from their 10-day honeymoon in the Seychelles and for their first royal engagement they met with President Obama and the First Lady. So what did two of the most influential women in style wear to meet each other?

If you thought Kate would ditch her high street standbys for designer dresses now that she’s a Duchess and doing things like meeting the President and First Lady, think again. She looks gorgeous (and quite thin) in a simple $340 camel bandage dress called the Shola, from one of her favorite brands, Reiss. Kate famously wore Reiss in her official engagement portraits.
