I know this is an older thread, but in the midst of this heatwave, getting tips for clothing for hot weather is always helpful. I’m a big fan of the brand Spunkwear. They have dresses, skirts, tops, etc and they’re made with bathing suit material. I’ve worn them at Disney and Universal and they’ve been great. Plus if you get wet on a water ride, they dry easily like a bathing suit.
My first encounter with these were at a lacrosse tournament. It was 105 in the shade with NO breeze. My cotton shirt, shorts and underthings were drenched and I was incredibly uncomfortable. I saw the dresses on sale at a vendor booth, bought one and changed right in the porta-potty. I was THAT desperate. They’re not cheap, but last along time and have been worth the cost. Especially on a hot, humid, sticky day.
