Spring Wardrobe

Each year I always go through the same fight with myself, what is the spring, aka, really flippin hot in April through October in the desert. How on earth does one look chic, simple, when it is over 100 degrees. I have lived in Las Vegas for 10 years and I still don't have it down. I can't really do the casual flip flops (I really hate them), denim bottom and tank top uniform that many ladies, who I'm afraid are having the same problem as me, they just don't know it.

Is this possible to look pulled together, without showing too much skin, and still having some sort of personal style, without falling into the "Bad Las Vegas Fashion" that I still shake my head at!
