I'm taking a fashion course this summer I'm planning to make some diesel punk gear for myself. Also sorta off topic I'm making a WW1 gas mask out of clay for my final in Ceramics.
I live in PA and have never been to Texas, but ince we have something hear called "the island effect" which makes it really hot here. On most days I'd wear cargo shorts or capris, frm regular stores not army surplus, but I plan to get some stuff their soon.
Hot weather's rough on style. When I lived in Arizona for 2 years, I learned a bit about hot-weather clothing. I found that a hat could make the difference between a tolerable day outside, and death by sun and dehydration.
Also, when it was 107+ that a long-sleeved shirt was more comfortable than a short-sleeved one. Sounds backwards, but a long-sleeved shirt works a bit like a personal evaporative cooler.
Just wear good deodorant...
