For the outing, Pippa wore a coordinating red ensemble underneath a black coat, accessorizing her look with a matching clutch and heels and a pair of earrings.
Just like her sister Kate Middleton, 40, Pippa loves to recycle a good look. In fact, the red top and pants appeared to be the same pieces she wore to the launch of James' brother Spencer Matthews' non-alcoholic spirits brand CleanCo. in 2019.
As for James, he sported a navy suit and light blue shirt for their viewing of the Cirque du Soleil performance.
Pippa and James marked their fourth wedding anniversary last May.
As fans may recall, they tied the knot at St. Mark's Church in Englefield, England in 2017, with the bride walking down the aisle in a custom lace gown by Giles Deacon, a tulle and pearl veil by Stephen Jones and a Maidenhair Fern tiara by Robinson Pelham. Kate and Prince William's son Prince George served as a page boy while their daughter Princess Charlotte was one of the bridesmaids (the Duke and Duchess of Cambridge's youngest child, Prince Louis hadn't been born yet).
