I've just completed my 3rd summer in south Texas, where the temps can start passing 100F/38C in May and stay that way until September, with a another month or two averaging in the 80s and 90s F/26-35C, and that's before taking into account the humidity. I hate it, so you have my complete sympathy. I have worked out a few formulas, though...for me I also prefer not to suntan, and sunscreen doesn't always cut it, so when I'm out and about I cover up my arms (my legs don't tan as quickly for some reason). So, here are my 'uniforms.' One: mid thigh shorts (fairly roomy so as to de-bombshell their length) + boxy, waist surrending, lightweight, high necked (for sun coverage), woven natural fabric blouse (to allow a ton of airflow...I'm small chested so as long as I choose wisely I can secretly go braless beneath these tops which helps keep me cool) + long sleeved cardigan in cool natural fabrics that isn't too fitted (worn either open or with just the top button buttoned) or super lightweight long sleeve linen jacket. Two: the same blouse & cardigan/jacket but with lightweight. slim-but-not-skin-tight cotton trousers (usually capris). Three: either the trousers or the shorts with a long sleeve light weight blouse, thus eliminating the need for a cardigan. Three: airy woven cotton dress knee length dress, with cardigan/jacket for sun protection. I also have a few summer hats to feel more pulled together: it took awhile to find ones that were cute and also actually shaded my face & neck but it was worth it. They instantly turn a top & blouse into an outfit. Since it's too hot for most accessories, I make sure my blouses have interesting patterns or colours or details like pintucks to stand on their own. I also use brooches, since they're not touching me! Oh and I make sure I have all of my outfit ingredients in a few different colours so I can play with colour combos. I live a casual life, so my shoes are almost all casual flats, but they're nice leather and mainly in darker colours, which I think makes them look a bit more intentional.
Woven clothes seem to automatically look a bit fancier/more intentional than knits and they're SO much more comfortable in hot weather. They've become my secret weapon. Hope that helps!
