I would wear shorts and a comfy shirt i wouldn't wear a skirt because it might get hot and sticky under your legs and I've worn skirts in cars before and it wasn't comfortable.
Just wear something comfy like shorts & a tanktop.
you should were sport clothes
sounds fine but maybe try shorts rather then the skirt and change in to the skirt later
I would not wear a skirt, my family and I took a car trip for 10 hours and I wore a dress. It was so uncomfortable. Is wear shorts and a tank top :) have fun!!
