I'd recommend slacks and a simple blouse. Sweater and or jacket depending on the weather (hit the Exchange for a fleece!). She wouldn't wear jeans to a job interview. She will be evaluated and reported on, so she needs to make a positive impression. For instance, my son rough-housed with the 3/C (longer story about carry-on for 4/C), and kept his mouth shut when his cadet had late rack and forgot to get him to breakfast. On the other hand, another kid fell asleep about 6pm. Just crashed. Not a good impression.
