Nothing inspires obsessive shopping behavior as much as buying a designer bag. Given that most are a big investment and are well into four figures, there is saving to be done, colors to debate, and styles to track down. Classic hues like black, brown, and navy are top sellers owing to their closet longevity, especially in larger carry-all sizes. But lately, designers are producing smaller styles that, while not cheap, are more affordable. Zip-top pouches can be found by everyone from Proenza Schouler to Givenchy to Victoria Beckham. In vivid colors like rich red and bright green, and patterns like houndstooth and colorful leopard, they feel like a luxury treat without requiring the commitment of a big splurge. Toss one into your everyday tote and bring it out for a quick coffee trip or a nice lunch. Some, like Prada's bejeweled version or Reed Krakoff's sleek, black patent-leather pouch, can even double as a chic evening clutch. And unlike a more standard minaudière for night, these will fit more than just a cell phone and lipstick. Click ahead to start browsing.
