You’ve Seen Kate Middleton’s Blue Long-Sleeve Dress Before — Here’s Where

You know the Duchess of Cambridge loves an outfit when she wears it more than once. Kate Middleton's blue long-sleeve dress has been hanging in her closet for years, originally making its debut during the royal tour of Canada in 2016. The Duchess just re-wore one of her favorite frocks, and styled it in a fresh, new way.

Middleton visited the Imperial War Museum in London on Wed. sporting a fitted blue number that only the most attentive royal fans would have recognized. The familiar frock was, indeed, the same piece she wore during her and Prince William's official tour of Canada two years ago, although it looked quite different back then. The midi dress is by British designer Jenny Packham, who Middleton wears constantly. Its sheath silhouette is accentuated by a thin built-in belt around the waist, while its bell sleeves and puffy shoulders give the dress a subtle flair. When the Duchess first wore the dress, the neckline was adorned with a flat pointed collar, which appears to have been removed for her most recent look.

While the mom-of-three originally wore the piece with a silver maple leaf brooch that belonged to the Queen and a formal fascinator, this time, she sported it in a more casual way, with her hair down in loose, carefree waves. Both times, however, the Duchess paired the dress with matching nude-suede pumps and a clutch.

The 36-year-old has a thing for recycling clothes. She's been known to wear the same pieces over and over again (see: the Penelope Chilvers boots Middleton has been wearing for 14 years). She even re-wears old favorites to other people's weddings, including the Catherine Walker coat she wore to friend Sophie Carter's nuptials and the cream-colored Alexander McQueen coat dress she famously sported for the fourth time at Prince Harry and Meghan Markle's wedding in May. You can almost imagine the Duchess asking "this old thing?" as she sports her favorite recycled magenta Mulberry coat or the baby blue silk-satin dress she has worn repeatedly over the past six years.

The royal is loyal to her brands, too, and Jenny Packham is one of her go-tos. The designer has been involved in many of Middleton's most iconic moments: introducing both Prince George and Princess Charlotte to the world for the first time, her first ever state banquet dinner (during which she paired a Packham gown with the historic Lover's Knot tiara), and the 60th anniversary of the Queen's Coronation Ceremony in 2013.

Middleton has been wearing the designer for about a decade now, having more than 20 Packham dresses currently under her belt (and still counting). And with the most recent re-wear, she's proven that with just a few modifications, you can absolutely take those formal frocks collecting dust in your closet — bridesmaid dresses, anyone? — and make them street-ready. A simple removal of a collar or raise of the hem, for example, could help adapt a gown to your work wardrobe. If the Duchess can re-wear her most famous ensembles, so can you.
