My favorite fashion: Modest clothes that cover my body 

It is extremely hard for me to find professional clothes that cover my entire body, short of wearing pant suits everyday. Why are there no pencil skirts that go all the way to the ankles? Why are there not dresses with sleeves and tights to go with them? The one time I can pull that off is in the winter so my question is what about the rest of the time? I live in Texas and it’s hot 95% of the time and I cannot dress modestly and professionally.
