Kate Middleton wore Blue Zara Blazer @ Winsdsor Family Hub

Kate Middleton  visited young families in Windsor as part of her continued interest in early child development, wearing another one of her trademark Zara blazers for the occasion.

The Princess of Wales, 41, debuted a blue-and-white houndstooth jacket for her outing today, with the past-season style retailing for $90 before it sold out.

She wore the double-breasted style with navy L.K. Bennett trousers, her frequently worn white Ralph Lauren top and a new pair of deep blue flats ($440)
