Wear is the degradation of materials over time, primarily in the context of food and clothing. Wear will alter the quality of an item, denoted by the symbols x, X and XX. For example, over time a dwarf's "Pig tail shirt" will degrade into a "xPig tail shirtx" and eventually a "XXPig tail shirtXX" before disappearing entirely. If this happens to a piece of masterwork clothing, the dwarf who created it will get an unhappy thoughtVerify.
Masterwork clothes items created together will all wear out at the same time which can drive the craftsdwarf mad. To avoid this, you should sell tatted masterwork clothes to caravans early enough. They are still worth good moneyVerify:

Animal-based products can rot, which is different from wear (see miasma). Crops and harvested plants can wither if not stored in a stockpile, making them useless but generating no miasma.
Notes on wear:
- Clothing that is being worn will wear out, over time, due to normal usage. This happens regardless of material.
- Armor does not wear out, unless it's kept in a refuse stockpile.
- All clothing and armor in a refuse stockpile will wear out. This is intended as a means of destroying old used clothing that would otherwise make dwarves grumpy.
- Clothing and leather items are worn down very rapidly after catching on fire.
- Trolls can beat on doors, wearing them out until they break.
- Wood and cloth items in a trade depot built outside in a glacier biome will degrade until purchased. This will also happen to items in a starting wagon in a similar location. Walls do not halt the effect.
- Invaders' clothing is also subject to wear.
- Cages do not prevent wear.
All improvable items made from creature or plant materials (i.e. cloth, silk, leather, yarn, or wood) will gradually wear out over a very long period of time, even if just sitting in stockpiles, gaining one level of wear every 100 years. This is technically a bug - cloth/leather items are supposed to wear out at 5 times this rate.Bug:6003
