Only thing constant in life is change and very much the same applies to nail art. It has been in practice since ages and was primarily done by males only. Eventually times changed and the art shifted to ladies only. People used gold and silver and later on colors were experimented with.
If you have been constantly observing the nails of different ladies, you might have registered that many trends have been introduced. One such form is the striped nail art. They not only look different but attractive too. At least they are much better than the old subtle single shades
Nail art may be done in a number of ways. You may make them look shimmery, floral nails art, use of glossy shades, using multiple colors to enhance the look and many more such forms. The designs are nothing but what you imagine and how you imagine.
Nail art speaks a lot about the personality that you have. For instance sparkles represent that you celebrate each and every day, triangular shapes represent that you are open to changes and have a flexible nature, and so on and so forth. So see for yourself how and what you are and then blend the shades accordingly.
