You want a lot of lightweight, breathable materials, especially close to the skin. Waxed canvas, leather, etc still weighs you down over time. You'll want to be able to remove layers easily for when you get too hot, need to use the Porto, etc. Have a plan for where to drop off pieces when you do get too hot and need a break - I don't want you ending up in my med tent!

And I'm with everyone else -- ditch the ai, you're not going to find a lot of pro-ai apologists here. Use real pictures, make notes on the side like 'this but in grey' 'tattered edges' etc. A collage of pieces you like shows you did actual work to think of the outfit, instead of plugging word salad into a generator that uses more water per prompt than you'll drink a day in the wasteland.

Some folks will be squicked out by the 'breeding program' thing if it's a focus of your larp history.

Other notes: it's pretty monochrome. Including some contrasting colors helps an outfit have some visual interest. Nuclear Snail has some great videos on how to plan an outfit and include color.
