Tracing the origin of flats through history is more complicated than other shoe styles, such as high heels or wedges. Even the earliest shoes man first made could be considered flats. In fact, when archeologists discovered Tutankhamun's tomb, they found several pairs of pure gold flat shoes the Egyptian king would have worn when he ruled. However, the flats that bear the greatest resemblance to the shoes we wear today made their first appearance in the 1800s when men and women alike wore soft, simple slippers.

Flats for Casual Outfits

One of the biggest advantages to flats is that they're perfect for keeping feet comfortable all day long. If you know your girl has a big day planned and she'll be on her feet a lot, consider a pair of flats from brands like Janie and Jack or Gymboree. If your girl is wearing a pair of jeans and a T-shirt, you can select a pair of slip-on flats that look like sneakers or a pair of girls' sandals.

Perfect for Everyday Wear

For those outfits that fall between formal and very casual, flats are the perfect way to pull the look together. Take a pair of cotton pants or another type of casual pants and match them with a bright blouse. If the weather is cold, this outfit will look nice with a pair of girls' boots, but on warm, sunny days, go for a pair of cute flats that resemble ballet slippers to complete the look.

Good for Dressing Up a Formal Outfit

While girls' dress shoes are a great option for when your little lady is wearing a dress to a formal event, they're not the only choice you have. Whether you're attending a wedding or party, you can also pick out a pair of flats so her feet will stay comfortable no matter how much dancing she does. You can go for a fun pair of flats that have extra details like ruffles or sequins, or you can go with simple black flats that will match any outfit.

If you want to put together a formal outfit around a pair of flats, consider a dress that has details or colors that match the shoes. You can opt for a long dress or one that hits around the knees. She can even pick out fun extras like a small purse or costume jewelry to accessorize her look just like an adult.
