Hobo bags mimic the style from handbag fashionistas. The OiOi hobo diaper bag, for example, has one main internal compartment and a shoulder strap with an adjustable buckle.
Convertible bags, such as the Ju-Ju-Be BFF, come with a handle and a removable sling strap and backpack strap so you can use it in whatever mode is most convenient.
If you want wear your baby gear around your waist like a carpenter belt, you can get a fanny-pack style, like the Mia Bossi MB601 Tobey Diaper Bag.
Some sling-style bags are designed to be smaller for quick outings. Like a messenger bag, it has a strap that can cross your chest, but because it's compact it can fit snugly.
Last and least are mini bags, which are made to fit inside something else. They look like a small handbag or clutch, such as the Cross Town Clutch by Petunia Pickle Bottom or the Amy Michelle Poppy Chic Diaper Clutch.
As you're realizing by now, there are enough different types of diaper bags on the market right now to warrant their own edition of "Project Runway." Parents can choose one that looks practically professional, a mod messenger bag, a hike-worthy backpack, a small sling, such as the Mothers Minder Sling Bag, or a tiny "changing purse" such as the clutches mentioned above. Some bags hold only a few diapers and are made for quick outings; others are big enough for a four-day getaway, with zippers to let you expand the bag when you need more room.
Before you're seduced by all the choices in shape, style, fabric, and fashion, think about where you'll be bringing the bag and what will work best for you. An imported Italian leather fanny-pack style like the Mia Bossi Tobey might look chic when taking a walk to a local coffee shop, but you'll want something more substantial for a day trip, when you need to pack an extra outfit for your baby, your cell phone and wallet, and a day's worth of juice boxes or formula.
Practicality is paramount, but a diaper bag can still be a fashion accessory. If you want that silk-covered bag with great graphics and colors, just make sure the interior is nylon or microfiber so you can clean up after the wet diapers and spilled milk. Ju-Ju-Be bags, for example, are machine washable, have light-colored interiors that make it easy to see inside, and are easy to wipe clean. Plus they're treated with an antimicrobial finish. In the mood for a bag with a camouflage design, your alma mater's insignia, or even a skull and flames? It's all out there. You can also easily find something more subdued but modern, like stripes or polka dots. You'll have to look a bit harder for those old-school, sweet-and-innocent designs like butterflies or Winnie-the-Pooh, but they can be found, too.
