Though Kate Middleton may be a royal style maven, she's not afraid to re-wear her outfits—even if they've been previously seen at the biggest wedding of the year.

At Prince Harry and Meghan Markle's nuptials this year, she wore a cream Alexander McQueen coat dress that she'd already reportedly worn at two other occasions (perhaps it was her way of avoiding outshining the bride). Today, nearly two months later, the Duchess of Cambridge revived the look again, but in a different color.

Middleton arrived to the Royal Air Force's 100th anniversary celebrations in a pale blue coat dress, featuring a similar silhouette and lapels to her royal wedding look. Like many pieces in her wardrobe, this number was also by McQueen.

Aside from the color, some subtle details kept the outfits from looking identical. For example, Middleton's dress today featured shorter sleeves and a more fitted skirt. Though she wore nude pumps on both occasions, she accessorized the icy blue dress with a netted matching fascinator instead of the wider brim hat she wore at the wedding.

She also toted a structured clutch with a butterfly clasp, since she didn't have to look after young members of the bridal party (like Princess Charlotte) or carry any wedding flowers.

To finish off the whole look, she kept her hair in a neat updo and wore a massive diamond and ruby brooch, which she received from the RAF when she became an honorary Air Commandant in 2015.

Whether she's dressed for work or a wedding, the Duchess continues to kill the royal style game.
