Fallout 76 armor and clothing

Overview
In Fallout 76 the apparel system allows the player character to piece together their outfit from a variety of clothing and armor choices. The system is primarily broken up into 11 standard slots, and 5 layers.

Armor, body suits and power armor will be subjected to condition degradation. When the condition of any piece deteriorates to 0, it breaks and will offer no protection. Broken armor and clothing can be repaired using scrap at any armor workbench.

Many of the armor and clothing sets also have minimum level requirements before they can be equipped, including power armor parts. Power armor chassis are not leveled, so removing higher level parts will allow entry.

Characters can enter power armor wearing any combination of clothing, adding an additional layer of armor. However, wearing power armor nullifies all bonuses provided by the lower layers.

Underarmor
Underarmor is upgradable apparel that is layered below equipped armor and outfits. Each underarmor is assigned to a single lining group, each with their own modifications which provide additional protection and grant SPECIAL bonuses. For example, the Vault 76 jumpsuit may only be modified with Vault Tec underarmor linings.

Outfits
Outfits can be worn over clothing and over armor pieces. Many of them are "skins," meaning they will just hide what's worn under them.

Full headwear
Headwear which counts as hats, eyewear and/or masks.

Other
Includes apparel that can be on the player character's fingers, arms, neck, etc.

Armor Sets
All types of body armor provide Damage and Energy Resistance in varying measures. Most can be modified with lead lining to also provide some Radiation Resistance. Robot, Marine and trapper armor provide Radiation Resistance without the need for additional modification.

Events and Legendary enemies (enemies with the "legendary" name and/or stars next to their name) have a chance to drop a piece of Legendary armor. These cannot be scrapped and have one or more legendary effects.

Unique Armor Pieces
Some armor pieces come with an unique name and pre-attached mods or legendary effects. They cannot be re-rolled using legendary crafting feature.

Body suits
Full apparel body suits, such as the hazmat suit and the Garb of Mysteries, will unequip any armor, outfit or underarmors. They cannot be upgraded with legendary mods.

Power armor
All pieces of power armor must be attached to a power armor chassis.
