i have some more ideas to add later tonight, but what about a scenario where Amy is so grateful to Uncle Stephen and Aunt that she wants to take them out to a nice dinner with the money she made from her job?
If good girl route, sensible dress and heels with both uncle and aunt
if bad girl route, sexy revealing black dress, stockings and heels (no panties)
if slutty girl route, same as above (no panties)
if bad/slutty girl route, something comes up at work and Auntie is unable to join, but Amy doesn't want to cancel because it's a hard to get reservation, so she goes ahead anyway.
Example of the dress/stockings/heels from Lara of Babysitters:
