Well, having long hair is a plus. One simple thing to do for a different look it to do it in dual ponytails like the 1st picture. Definitely easy to care for and flowers or bows can make it a little more girly.

Oh sorreee, I hit the wrong key and only gave u half an answer. Plus left out all the pictures. You also could try something interesting in a regular pontytail. Also, A braid is another fairly easy option and think girls look cute with braided hair. The nice thing about these options is you can change it up every once and awhile for a new look.

You could also get a whole new style of course, but it's hard to advise you without a picture.

you could try braiding your bangs, or maybe shower at night, then using mousse all over and braiding large braids (but not too large) all over, then keep them in overnight, and unbraid them to get some soft waves in the morning! You could also try a little pouf at the top and a bun in the back, or you could keep it down but stiff have a pouf. I have really thick hair and sometimes its a struggle!
