Hello everyone, I am posting on this community to solicit advice on avoiding heat stroke while not looking like a fool. Currently I own several 95% polyester 5% spandex short-sleeve button-ups as well as one 100% linen long-sleeve button-up. I find both to be quite suitable for hot weather, but would love suggestions that aren't T-shirts and button-ups. Additionally, what options are there for summer pants? And what actually looks good with shorts? When I wear them I look like a camp councilor - or worse, a kid attending summer camp. 
Feel free to discuss dresses and skirts as well, although I am personally not interested. Oh yes, and I suppose summer hats could be useful too. Thank you in advance.
Fitted shorts and t-shirts, or a masculine tank top (called a wife beater for some reason). But that is for an informal masculine look, not sure if that's what you want.
For shorts with regards to a more masculine look, the fit and length is very important, too short and you look like you found your dad's old basketball shorts, too long and it looks like oversized kids clothes. It also needs to hug the thighs well, but not be too tight. That's just uncomfortable and not a great look. But then again, that's just what I find looks good. You might not even want or need this advice if that's not what you're going for.
Oh and lots of sunscreen.
