Do you mean a Rydel Inspired style for school? (If you’re asking Rydel herself she’s not a part of this blog <3)

For an updo:

To crate this all you need to do is put your hair in a high pony tail, leave your bangs down and add a cute headband. 

Or for hair that’s down:

For this one you can either blowdry your hair upside down before you straighten it or lightly tease your hair near the roots.
