Fantasia for Retainers?

Is there any way to recustomize your retainers without dropping them and starting over? Now that they can be actually be customized and such, I'd love to re-do them, but it's next to impossible because of how full their inventories are. I don't think there is a way to re-do them, but there should be!

i would love to recustomize my retainer too

I would shiv a man in a dark alley just to be able to let my retainers get their hair cut by the Aesthetician. Let me toggle off their hats and I'd shiv a man and buy you a puppy.
