How to ask former employer for a job?

hello,

A couple months ago i was working as a Brand Ambassador for Hershey. Being a Brand Ambassador, you pick the days that you are available. Once I started school, I got caught up and got too busy so I had to quit.

Im on break and need to find a job for the meantime. Im a bit nervous about reaching out to my manager about working for her again.

How can I reach out to her politely?
