Looks like you guys beat me to it, but … we now have hats with hair.
We are still fine-tuning things, so only some hats will work with certain hairstyles. Some hairstyles will also get "squished" - just like they would in real life.
Some headwear (e.g. bobbles, horns) will require a different approach, so we are working on finding a way to wear them.
Can't wait to see all the new looks in the game as soon as it opens!
