pro tip: gandalf wears a ruana cloak, which is hilariously trivial to make and honestly just a really good piece of clothing even in modern times.
just get a big piece of rectangular fabric (as wide as your armspan, and 2x as long as the distance from your shoulders to the ground), make a cut down the middle of the short side, to the midpoint of the fabric, then sew a reinforcement at the seam so it doesn’t rip up when in use.

Then just pull it over your head and bada bing bada boom gandalf cloak

Yes, that is what they called me.

Literally how I attended parties in high school.

I wish I could be that popular, but I’d end up talking to the folks on the wall as I debate firework integrity.
