I'm going to make an HA for a character that is on the older side. I'm not sure how old but I'd like to know if there are any wearables that can age up an HA.

Can provide you a long white beard c:

That is a very fashionable white beard =D

I'm not sure on items for specifically that like wearable wrinkles, (maybe we are missing older HA options on subeta?), but I think layering a few items that give your HA a more sunken look to the face, smaller eyes and thinner lip types, can help with that. Mostly anything that goes opposite to neotenous traits. Also very thin brows if its female presenting HA:

+ might also help a bit if you're planning on using a light skin base

Some of the costume trunks have older characters, all male.
These item from the trunks might help.

Thank you for the help.

Don't know if I got an old look or just traumatized xD

Perhaps a bit of both? xD And you're welcome!
