Her first away mission

Julie is going to get her chance to mingle with the denizens of the Galaxy, but where, with whom and under what circumstances?

A couple of suggestions:

1) The ship stops at a busy space station and Julie is sent out to collect supplies and run errands.

2) Julie is assigned to serve the Captain on a diplomatic mission and we learn what Julie's formal dress uniform looks like

3) Julie explores a newly discovered world as part of an away team. Fortunately the planet has a breathable atmosphere, so she gets to go down there in nothing but her pasties!
