"The Devil Wears Prada," but when it came to her big day, actress Emily Blunt opted for a Marchesa.

The British beauty donned a Marchesa Bridal custom cream chiffon sweetheart draped wedding dress with embroidered detailing as she exchanged vows with "The Office" star John Krasinski on July 10, Us Magazine reports.

We'll bet it looked fab with her gorgeous 3-carat Edwardian diamond and platinum Neil Lane engagement ring, worth a reported $75,000 - $85,000. (Here's hoping she gets to keep hers.)

The couple tied the knot in a private outdoor ceremony in Como, Italy, home to wedding guest (and former Krasinski co-star) George Clooney, sources tell the magazine.

Marchesa, Neil Lane, and Clooney? How lucky can one bride get? We'd have been excited to get Dwight Schrute.

Marchesa -- celebrity fans include Sarah Jessica Parker and Sandra Bullock, who wore the designer to this year's Oscars -- launched its bridal line after co-founder Georgina Chapman designed her own wedding dress to marry movie mogul Harvey Weinstein.

And while photos of blushing bride Blunt have yet to be released, we have no doubt she looked stunning. Eat your heart out, Pam.

Meanwhile, get the details on new bride Carrie Underwood's wedding dress.
