Country star Miranda Lambert channeled her Kentucky Derby look this weekend from a world-famous hat expert: Catherine, Duchess of Cambridge! “She definitely looked to Kate Middleton for her Derby hat style,” her stylist Tiffany Gifford told InStyle.com of her Giovannio New York topper. “Miranda specifically asked for a fascinator this year because the big hat she wore last year was so heavy it hurt her neck! She loved the little cage on the front because it was just the right amount of retro.” The black sequin-covered topper complemented her printed Lela Rose strapless dress, while red Charlotte Olympia pumps and Colette jewels rounded out her accessories.

Duchess Catherine wore a blue tweed Rebecca Taylor skirt suit to an event in London today, and we caught up with the New Zealand-born, New York-based designer to get the inside scoop on dressing the royal. “I thought she looked impeccable as always, very clean,” Taylor told InStyle.com. “I’m such a royalist, and I think Catherine is so perfect for the royal family. She’s got such style.” We agree! Next on Taylor’s agenda: “It’s early morning in New Zealand, but when my mum and dad wake up, I’m going to call them,” she said. “They’re going to freak!“
