Uncanny Outfitting (5e Spell)
From D&D Wiki
Any armor or attire you are wearing is instantly doffed, and at your option any armor or attire stowed on your person is instantly donned in its place. The armor or attire you doff can be stowed in an appropriate place on your person, or dropped harmlessly at your feet. For the purpose of this spell, you can don or doff any shield as if it was part of your armor.
