Wearing and Wielding Items

Using a magic item's properties might mean wearing or wielding it. A magic item meant to be worn must be donned in the intended fashion: boots go on feet, gloves on hands, hats and helmets on a head, and rings on a finger. Magic armor must be donned, a Shield strapped to the arm, a cloak fastened about the shoulders. A weapon must be held.
In most cases, a magic item that's meant to be worn can fit a creature regardless of size or build. Magic garments are made to be easily adjustable, or they magically adjust themselves to the wearer.
Multiple Items of the Same Kind
You can't wear more than one of certain magic items. You can't normally wear more than one pair of footwear, one pair of gloves or gauntlets, one pair of bracers, one suit of armor, one item of headwear, or one cloak. The DM might make exceptions.
Paired Items
Items that come in pairs-such as boots, bracers, gauntlets, and gloves-impart their benefits only if both items of the pair are worn. For example, a character wearing a Boot of Striding and Springing on one foot and a Boot of Elvenkind on the other foot gains no benefit from either.
