It’s a royal fashion faux pas!

Kate Middleton looked lovely in a blue coat while attending a wedding in Chippenham, England, on Saturday, March 29. But, then again, another wedding guest also looked lovely in the same M Missoni style — gasp!

While it was just the coat that matched, we’d venture to guess that the similarly dressed wedding guest (whose identity has yet to be revealed) may have gulped when she spotted the Duchess of Cambridge, 32, at the nuptials of close friends Lucy Meade and Charlie Budgett.

Middleton has been spotted in the blue tweed topper from the Fall Winter 2010 collection at least twice before. She wore it to the final Royal Jubilee tour stop in Nottingham in June 2012 and also a few months before when she met grandmother-in-law Queen Elizabeth for tea in March.

Princes William and Harry also attended the wedding, although were spared any Who Wore It Best moments with their fellow guests.
