|This is my attempt at the "squoval" shape.|
If this describes you, then you might be better off trying to work around the issue to best suit your needs instead of trying to follow the pack. The outcome may pleasantly surprise you with how much younger your hands may look.
Instead of the square-shaped nail, I suggest altering it into a “squoval” shape. By this, I mean that shape is not entirely square or purely oval but in between. The look is more classic and chic.
Another recommendation is rethinking the length of your nails. You may have kept them long just a few years earlier, but you should consider adapting to a shorter length beyond your fingertips. This will further help protect them from breaking but also give your nails a timeless, graceful look.
Just as important to aging hands is the color you paint your nails. Though wild, shocking colors of nail polish can be fun, you might want to save those shades for your toes and switch to pale, sheerer shades such as light pink or beige. The reason is light colors seem to lengthen the look of the nail compared to bright shades that can make the nails appear shorter.
