be in good taste
To be appropriate or acceptable (resulting from good judgment by the person who said or did such things). Consider your audience—comments like that are just not in good taste. I don't doubt that the sculpture was in good taste, but I don't think it was done well.
be in the best possible taste
To be completely appropriate or acceptable (resulting from good judgment by the person who said or did such things). If you want to avoid more controversy, don't say anything to your audience that isn't in the best possible taste.
