If you want to keep your hair wavy over night, or out of your way if it's hot, or both, here is a cute style that works well, and stays in good. You can do it dry, or wet.
Pull your hair over one shoulder.
Secure with a loose elastic.
Next, you will fishtail braid. Separate your ponytail into two sections.
Take a strand from one section,
Cross it over, and give it to the other section.
Then take a strand from that section, cross it over, and give it to the other section.
Repeat all the way down, and secure with another clear elastic. There you go!
