Beauty curios represent a wide range of features that can be worn. They are part of Feature Curios (See HELP FEATURE CURIOS) and when worn increase prestige for influence battles. Below are the possible features:

Suitability is defined as suggested usage, but other combinations are possible. Anything marked 'vague' does not use the word skin, and as such could in theory be easily found on someone with fur, scales, chitin, etc. Anything marked 'skin' mentions the word skin.

Beauty curios do not have built-in emotes like hair and beards, and they do not have pre-defined colours in their descriptions to ensure they match a wide variety of appearances easily.
