This weekend, Kate Middleton wore a blue brocade jacket to Prince Philip's 90th birthday that looked very familiar.Kate Middleton (Getty Images)
The Duchess of Cambridge attended the church service and reception on Sunday at Windsor Castle in a blue jacket with a matching dress and fascinator. But we knew we'd seen the coat before—she wore it to a friend's wedding back in 2009. Look out Michelle Obama, we have another thrifty trendsetter on our hands!Related: Pippa Middleton's changing style

It's a gorgeous coat, so we can't blame her for wearing it to another big event, and it certainly maintains her accessible image.Related: Kate Middleton's dazzling dress
