Kate Middleton recycles her outfits so often because she's a classicist. She knows what works for her, and she sticks with her streamlined uniform when she makes an appearance. There's nothing wrong with that. If you've got a gal pal who tends toward the same routine, buy her pieces that are worth the investment. She'll never grow tired of them, and you'll be able to see just how much she appreciates your gift when she wears it time and time again.
