French manicure means that in the leading edge of nature, a line with a perfect arc is depicted clearly and accurately with a single nail polish, and the width and arc of a pair of hands are kept in visual consistency. It is not ostentatious and has little embellishment style which makes it popular all over the world and become the universal manicure language all over the world. On the basis of French manicure, many kinds of fancy manicure styles are gradually derived.
The most suitable shape of French tip nails is square or squoval. Oval nails are not suitable for French tip nails, because such a "smile line" arc is unlikely to be perfect. If you can only draw "zigzag" smile lines, you can paste water diamonds, pearls and other decorations on the edge of the dividing line to make up.
