Sounds like an excellent place to start!
It's not so much specifically regency or specifically Victorian, it's just generically anglophilic- either the virtuous helper with the family business, or the innocent debutante, works well.
Where do you see her as ending up? What are the things she's inhibited about?
The theater has a fairly broad clientele in terms of social class- it's part of what makes it both popular, and infamous, that you can stop by and see how the other half lives (or at least, how they watch a play).
