The only way to make the pastel nail designs look soft and feminine is firstly to cut your nails in oval shapes, almond or rounded ends to look smooth and not harsh. Put on a base coat to cover the nails and even out the pastel shades. Use light pastel colours (lavender, mint, baby blue, peach or soft yellow) and pick one shade or combine several thereof creating a toyish effect. Work in thin layers so as not to streak, but to have a light airy finish. To add some extra appeal, incorporate such small elements as small florals, dots, or simple line art in white. Lastly is a glossy or sheer top that will add softness, elongate wear out and make the manicure not only feminine but elegant and easy as well.
