Striped nails are another fun idea for geometrically inspired nail design. Stripes can go in any direction: horizontal, vertical and even diagonal. If you fall for a romantic manicure, consider pink and white nails with stripes. This mani is very easy to get. All you have to do it to polish your nails with pink nail varnish and then add white stripes using a thin brush. For an added cuteness, accentuate one finger with a heart depiction and write something sweet, such as “love.”
