Nail shapes refer to the various forms that fingernails can take, each offering a unique aesthetic and style. Common shapes include square, oval, almond, stiletto, and round. Each shape can complement different hand types and personal preferences, influencing the overall look of the nails. Choosing a nail shape can also affect the durability and maintenance of the nails. For instance, square nails are often more robust and less prone to breakage, while stiletto nails, though stylish, may require more careful handling. Ultimately, the choice of nail shape is a personal decision based on individual taste and lifestyle.
