Girls, what do you wear under dresses?

Make sure that you wear a nicer pair of panties in a color that won't be very noticeable if they happen to show. Don't wear a color such as white, yellow, or pink unless the dress is the same color. I like to wear short dresses in the summer and I imagine that I sometimes show more than I should. When I notice other girls white panties showing I think it looks kinda tacky. I have a couple of sundresses that are made so that you don't need a bra which solves the problem of what to wear on top under them.
