2. Prepare your fingernails
Shape is very important when it comes to a good manicure. While the trending nail shape may change over the years, the slightly squared off look is best for French manicures.
You can achieve this by gently filing the nail flat at the end and then rounding the corners slightly. Always file from the center of the fingernail and move the file toward the edge. Moving in this direction will help prevent splitting nails and irregularities that can cause breakage later on.
