Queen Máxima of The Netherlands, queen of accessories [1] and unexpected royal looks, is at it again! The Argentina-born ruler [2] just wore the epitome of the Summer dress to christen a cruise in Rotterdam — that's the sort of thing you do when you're a queen, we guess.

We immediately had visions of wearing a similar dress to a Summer wedding, a Caribbean vacation [3], a cruise lunch outdoors, and a very fashionable day shopping. If you're as obsessed as we are, you'll be happy to find a few options to steal her look straight ahead.
