We all remember the sight of Kate Moss sloshing through the mud at the Glastonbury music festival years ago, mostly because she instantly created a fashion frenzy by wearing a pair of black rain boots. Since then, rain boots have become the boot du jour for those living in rainy climates, which is why the latest designer collaboration—between flip-flop brand Havaianas and British designer Matthew Williamson—is so exciting. The collaboration features two styles of rain boots: Blue Rain, a brightly printed boot; and Black Peacock, a darker boot with a bright feather print. We are finding it hard to pick between these two prints, but one thing is certain: no matter which we wear, we are sure our rainy days will be dreary no more. To check them out, head to HavaianasUSA.com. Each pair retails for $125.
