Eternity Ring (and glamouring)

They do warn about the rings. Multiple times. Before entering the chapel, and again if you talk to the concierge, I think.

Shame because the gloves are given as part of the entire ensemble but you can't actually use them.

Well you can use Coronal Wristband which makes you can see your ring

You can also use leather wristbands, much cheaper than coronal, and they are near invisible with long sleeves.
