To alter or not to alter. . . that is the question.

So here is one of the personal purchases I made on our trip. . . A beautiful blue velvet mini-dress I found at a Vintage shop in Montana. I'm thinking of wearing it to a wedding that I'm going to next weekend.  The question is:  to remove the bow or not?  I kind of feel like 28 is too old for large satin bows. . . but then there's the ethical dilemma of altering pristine vintage pieces.  hmm. . . any thoughts?
