Trial Fantasia

[Seraphor]

To be fair, you can't test out every hairstyle or emote that way. You can only do so on your main character.

Buy a Retainer Fantasia. You can dress them in any of your gear (that they can also equip) to try out glamours, and I expect they can use any hairstyles you've unlocked too, although I haven't tested that.
Then, you can see what they look like in the world, or at least in cities and housing wards, instead of the awful character creator lighting.

I wish we got one free Fantasia every year we stay subbed for.

I just wish Shadowbringers came with a free fantasia.
I'd have expected it to be listed in the pre-order or game description if it did, but nada.
Unless it's rewarded as a quest reward early on in the MSQ or something.
