Opinions: Do you wear your boots and tights in summer?

Since I am starting my very first actual job where I get to dress up, I was wondering what your opinions are on wearing boots (ankle boots/booties) and tights in the summer.. I am really getting into dresses right now, and Id LIKE to wear my booties but I don't want to look.. well... like a dork.. lol.

Also, I don't feel "right" without tights or hosiery under my dresses. Do you ladies still wear them in summer? My legs are sooooooooooooooooooooooo white! And I also have a tattoo that I'd like to lessen the appearance of.. But again, I don't want to look silly or die from a heat stroke. Are there certain types of hosiery that are better for summer months?

AND a question.. maybe another silly one. What in the world do you wear under dresses these days? Back in the day when I went to church every Sunday we wore those frumpy slips. Now bear in mind, I still down one.. But I'd rather be chic not frumpy.

I will love you ladies forever if you could give me advice! :)
