Kate Middleton Repeats Roland Mouret Dress... But Adds An Adorable Hair Ribbon (PHOTOS)

When we heard that Kate Middleton would be stepping out to attend the London premiere of "Mandela" today, we were excited to see the mom debut a new evening gown. But when we actually saw the duchess grace the red carpet, we were psyched -- Kate had gone and repeated one of our favorite dresses.

The white floor-length Roland Mouret gown features slightly ruched shoulders, an off-center back zipper and a pretty high slit for a royal. Kate accessorized the sleek look with black pumps, a black clutch and a glitzy necklace from Zara. But the best personal touch had to be the black velvet hair ribbon (we know) that secured her chic ponytail.

While we admittedly preferred the glittery Jimmy Choo heels she wore the first time we saw her in this dress back in 2012, we'd say the adorable hairstyling this time more than made up for the lack of shoe sheen.

Oh, and we assume two tiaras in one week would've been too much to ask.
