There are a few pieces of Ötzi's clothing that I did not attempt to recreate. Partly because his clothes require a lot of available material, and partly because, by this point, I was thoroughly ashamed of my crafting abilities as compared to my prehistoric teacher. Going from simple shapes to the complex construction of clothes, I think, is simply beyond the skills I've built so far.
Ötzi had a coat made of several alternating strips of goat hide. One day, maybe, I'll have the goat-seamstress abilities to make this wonderful piece, but not yet.
Ötzi was wearing a loincloth a simple rectangle about 6 feet long that was slightly narrower in the middle. It was tucked into his belt nice and snug to better hold the family jewels. Six continuous feet of soft leather is, unfortunately, a lot of material for something I don't think I'd be using very often. If I were to make the loincloth out of what I have available - thick cow hide - I have a feeling that I would be very uncomfortable.
The leggings would also require a lot of material, and while they seem simple, I get the idea that a comfortable pair of leather pants is a worthy challenge for a craftsperson with thrice my experience. I'm interested in the shape of the leggings, especially that little dangle at the bottoms - it seems like Ötzi had stitched on some hairy bits to act as shoe-tongues. The shoes were snug around the legging dongles, the leggings were tied to the belt, and the belt tightened the jacket. Makes you wonder how often Ötzi bothered to change his clothes.
