Use curling shampoo while taking a bath, and afterwards when it's dry, curl strands of your hair around your fingers to help it get in the mood.

Ending1: It's important for this preppy look that your hair is in the right mood. If you have straight hair, keep it straight.

[title] Get your nails. [step] The pink nails will keep you looking young and girly. Ending4: Also be sure to trim the ends of your hair, then you'll look older and tomboyish. [substeps] If you have short hair, use a wide toothed comb to dry the ends of your hair.
