If you want a flag belt buckle that serves as a piece of jewelry to improve your overall ensemble, expect that most of the American belt buckle designs are in cowboy themes. Even the confederate flag buckles, animal themes and 3D designs are mostly casual. The material used which can either be silver, pewter, brass or copper, adds to the laid back fashion. However, there are some military buckles, especially in plains which you can wear with formal ensembles. But regardless of the current trend or latest style, the versatile pieces will always be wearable. They include plain metal buckles or the plain horseshoe belt buckles, which are not removable, have the most versatile appeal. These are the kinds of buckles which you can use every day and with different outfit-be it casual or formal. However, expect these buckles serve as what it entails, and that is to keep your trousers in place. They may not serve as an adornment because the plain feature lacks the style of a fashionable buckle.
