Hi Leah, I'm in Sacramento where we have a similar hot and dry conditions, though a little cooler than Vegas, I think.
My recommendation is to get the lightest weight, 100% merino wool, long sleeve base layer or t-shirt you can find. 150 weight or lower, not 250. Get a good one that is soft, not cheap and scratchy. Slightly loose but not baggy is good. Women's often come in lighter colors, which is also good. Wool is sort of a miracle fiber, it wicks and breathes better than any synthetic I've found, doesn't feel clammy and dries quickly, and doesn't even need to be washed as often as other materials. It also hangs/drapes better than cotton. Bonus is that you can also wear the same shirt as insulation in the winter. I wear a long sleeve merino T or base layer as sunscreen on the bike, on snow, and on the water. It can still get warm, but the wicking and breathability combine to beat everything else I've ever tried. I've worn cotton, linen, ramie, and rayon in knits and weaves and some seersucker. None of them worked as well, or looked better with sweat marks, or dried as fast and comfortably as light weight wool. I actually wear merino dress shirts for the same reasons. I wish I had something as useful to suggest for pants. I still use sunscreen on the hands, and on the face and neck when a hat won't work. Sometimes I wear a buff or bandana for the neck instead.
