Ring of Invisible Dress (5e Equipment)
From D&D Wiki
Ring, uncommon (requires attunement)
This item superficially resembles a ring of invisibility, and attempts to identify the item identify it as a ring of invisibility unless the method of identification can identify cursed items. When a creature attunes to the ring of invisible dress, any clothing, armor, or other equipment worn on the body becomes invisible to all but the wearer. When such items are removed from the body, they become visible once more, and when the creature dons new clothing, it becomes invisible while it remains on the cursed creature's body.
When a creature attunes to the ring, it makes a DC 14 Intelligence (Investigation) check. On a success, they become aware of the curse, and they perceive their clothing as being translucent and faint while it is being worn. On a failure, they are unaware of the curse, and their clothing appears to them as it normally does. A creature that fails this check can repeat it when it completes a long rest.
