Square nails with sharp corners are another trendy nail shape right now. This is a powerful shape that draws attention to your hands, because it leaves the full width of the nail intact and makes a big statement. While it's the shape that's typically chosen for a French manicure, the large surface area also leaves plenty of room for painted patterns and nail jewelry. The downside is that the sharp corners tend to get caught on fabrics, so it works best on strong nails that aren't prone to tearing and breakage. This style seems to look best on long nails, as a shorter version can make hands look heavy and chunky.
