Shit maybe I should compile a list of tips and tricks for festival heat.
And you can still sew patches on your linen garments, you know. Get yourself a small messenger bag and a wool or otherwise fabric belt. Hang your soft flask (I strongly recomment soft flasks) off your belt and carry your phone and wallet in your little messenger bag. Once the temperatures cool and the sun fucks off, you can always tie your shawl to your bag strap.
I don't know if I'd recommend cotton shawls because cotton breathes but when it's wet, it stays wet longer than linen but it also traps heat, which is why they don't recommend cotton for underlayers when you hike. It stays wet, but also hot, it doesn't 'let go' of water at a proper rate, we tested it.
And it can't be a linen blend, not even with linen x cotton, has to be 100% linen. And then you have to consider the weave and fiber density. Heavy linen will be brutal, very light linen won't provide the air flow, and dries too fast.
My choices of colour wouldn't be full black. Dark grey, darker blues and reds and greens will do just fine.
And linen of a certain weight and looseness doesn't easily show sweat stains, again, because of the fabric's properties and the pit stank isn't as rank as it is with cotton and synthetics, esbecially bc with cotton, they often add 2-3% elastane which is good for daily wear, but real bad for hot weather sun blazing wear.
I saw so many people, especially women, in polyester. And choose a dress for a skirt or at least loose blouses and shirts. They catch the lightest of breezes and help you thermoregulate. Loose linen is good because it helps insulate. Insulate doesn't always mean protection from cold, but also protection from heat.
Idk just take care of yourselves, I saw some people suffering there. And no skin tight bare skin stuff. I don't care how good you look in it, and you won't either when you look like a trussed up broiler chicken sweating bullets. You can always go back to the campsite and switch into your bondage gear once the sun goes down. Too many people have been posting about how they had to skip bands because it was too hot on the festival grounds. Dress like the sun's your worst enemy.
And we had a thunderstorm on Saturday night, and if you had been wearing linen, your shit would've been dry by 8am!
Cotton shirts, man. The fucking enemy. Prioritise comfort. Sew patches on your loose linen stuff and your bag. Wear your jewellery. Just be smart. Especially when you hit your 30s age wise. I endured a lot of heat in my hot metal chick gear in my late teens, too, but the older you get the harder it is, and this is where I find you with your head in your ankles with your friends trying to shake you to see if you're ok, and you're unresponsive. And be very aware of when you stop sweating. Means you need shade and sips of water, even warm water, right now. Don't chug, you'll just pee it out or vomit it out. Small sips throughout, like your mother taught you when you first came home drunk and devolved into your first horrible hangover.
And keep a damp linen rag around your neck and head, temples and forehead, where the big arteries and veins are. Wet your inner wrists, too, same deal. Do like the kangaroos do when they lick their forearms to cool themselves down.
Edit I saw a ton of men in skirts and kilts though. They made the wise decision. The breeze is nothing to scoff at.
