Tell him by email voice mail or whatever that he will need to come get her uniform. Is him having D for this night a planned thing or is it a last minute thing? If it's a last minute thing then it should be even less of an issue for you. He's a parent too, he has to do some running around.
If he tries to manipulate you to get you to deliver it, simply say 'No' in as light hearted *nah, I don't feel like doing that but thanks for asking* tone as you can manage. He is a parent, when he has D then he should be responsible for all day to day stuff. You guys are separated, you are no longer running round to make things easier for him.
