Perhaps the problem is too much choice? Some kids get overwhelmed with options, I still do sometimes and I'm in my 50s! Is it possible to pull out two-three outfits the night before, let her cogitate over them, mix/match from them, etc. and then set it aside for the morning? Options are nice, but sometimes there needs to be more structure and boundaries to the process when there are a lot of other external stressors going on. Once she's comfortable with the day camp situation, you can reintroduce the complete wardrobe options again.
