WhileKate Middletonis no stranger to custom-madedesigner pieces, she also makes the occasional off-the-rack piece look absolutely regal. She did exactly that on Sunday while attendingPrince William‘scharity polo matchin Gloucester, England with her kidsPrince GeorgeandPrincess Charlotte.

One day after wearing abespoke Alexander McQueen dresstoTrooping the Colour, Kate, 36, wore a light blue, off-the-shoulder dress with white pinstripes that’s available at Zara (for now!) for only $70. The royal mom paired the sundress with a crisp white tote and a pair of neutral Russell and Bromley wedges, which she was still able to jog in when she ran to congratulate William, 35, after his game at Beaufort Polo Club.
