The portrayer, or a face-claim, is used to describe a character by their physical description, typically with a celebrity. For example, my character's name is Phoebe Ann Moses, played by Australian actress Isabel Lucas. 

Want to give them clothing that would fit the timeline?

Truthfully, I didn't expect your characters to be the "cunning-type". That's not to say that I don't approve, just pointing out that I did not see it coming. Let's just say that Phoebe is not the type to go around sleeping or teasing with anyone. She's quite humble and modest; an angel-like being with purity. But it would be possible that maybe the siblings could change their ways, ever since they've met her.
