William and Kate arrive in New Zealand with Prince George

The duchess's fashion choices are expected to be closely scrutinised during the tour and she arrived in New Zealand wearing a red coat with gold buttons - from British designer Catherine Walker, who was a firm favourite of Diana, Princess of Wales.

She teamed her outfit with a red pillbox hat designed by Gina Foster and a silver fern-shaped brooch, a symbol of New Zealand.

She has been loaned the diamond and platinum piece by the Queen, who had herself received it as a gift during a visit to Auckland 60 years ago.

Prince George wore a cream cardigan and matching shoes.

ここのteam A with Bは「コーディネートする」「合わせる」でしょう。ピルボックス帽（英: pillbox hat）はつばの無い、婦人用の小型帽ですが，これは写真をみて確認してください。ケイト妃はたくさんの「ドン小西」にwatchされて大変ですね。（UG）
