IT WAS ONLY A MATTER of time before we happened upon Julia Amory's Hamptons home in all its chintz-y splendour. Amory, her husband and their daughter split their time between New York City and the Hamptons, and it is this, their summer home, that we are in love with. Decidedly grandmillennial in style, it's a little new traditional with a healthy dose of grandma chic thrown in for good measure.
