To me, any behavior like that seems like it could impact your job security and if not that then for sure your work environment - She might be treated pretty differently now than she might have otherwise by coworkers. Some people may not respect her as much, and then there could be issues with certain gentlemen... Although any ensuing sexual harassment would certainly not be her fault, it might be enough of a catalyst for some creep-o to give her some seriously unwanted attention.

Frankly, a company sponsored party, alcohol or no, should be approached with inhibitions in tact if for nothing else than personal responsibility and sense of self-preservation. She should save that stuff for a night out with friends if at all.
