My girls are campaigning for short dresses, and I feel pretty weird about it. I get that *some* longer gowns can swing prom, but I can't shake the image of above the knee dresses as too informal to be appropriate (especially if they are strapless). It will be summer, so there is that, but we have gotten snow in July before so there is no guarantee that it will be super hot or not. If all goes well, we are looking at late afternoon ceremony and evening event -- are short dresses appropriate at all? Or are they too "daytime" or too much skin?
