Well, I once speculated which uniform William would wear--but I never thought he'd wear all of them! (No, not all at once.)
But for their getaway in the blue Aston Martin Volante, William is wearing the uniform of the Blues and Royals (his first military commision). And Kate is still in her gown.
We were sure (and still are) that Kate will wear something different for the evening, but we never thought William would be the clotheshorse.
I wonder if he'll make a public appearance in his RAF uniform?
