Hello. My name is Michael St. James, and I'm addicted to color-blocking. You're all probably sick of me fawning over this trend like it's the hottest thing since sliced bread, but at least I've fessed up to the obsession and I'm working on my recovery. Unfortunately, every time I think I'm cured of the affliction, a covetable bag comes along and sweeps me right back off my feet. Take the 3.1 Phillip Lim 31 Hour Tote, for instance. The simple design is flawlessly accentuated with a chic fold-over top, amped up further with ingenious use of color-blocking. On one side, this is a black tote with a hint of white, but on the reverse it's a white bag with a touch of black. In other words, you're getting two handbags for the price of one. Everyone from college students to corporate professionals and busy moms could effortlessly incorporate this large, timeless bag into their summer wardrobe. Purchase at NET-A-PORTER for $795. Also available in camel.
