This is the basic system. Details can be worked out later, such as resources to build a Clothier or a Tailor's Mannequin.
Players design a new style for characters to wear, hopefully using new art and character customization methods. The more extravagant the fashion, the more it costs. Simple styles involve linen, canvas, and leather, while more impressive fashions can take silver and gold wire, cut gems, and dyed silk.
In order to design a style, players need to construct a Tailor's Mannequin. The cost should not be too expensive; the real cost is in the fashions themselves. Because of obvious avatar limitations, separate styles must be designed for males and females.
Players must not only convince other players to wear their creations, but also provide the clothing. This can get expensive, but art has traditionally been an expensive discipline. Styles are aquired at a Clothier, which is a community building similar to the Sphynx. The cost to build it should be comparable to other such community buildings. One Clothier can hold up to 21 styles. It is up to the players to decide who can place their fashions in the Clothier once it is built.
Players accumulate points for every day their fashion is worn, per person wearing it, per material used on the fashion. Materials usable in the Test of Fashion are:
If you design a suit of just linen, and ten people wear it for two days, that's 20 points.
You can make a garment with Linen, Thread, and Gold Wire, which would be three points. If you got five people to wear it for a day, you'd get 15 points. If you got them to wear it for a week, that would be 105 points.
Or you could dye it. With three materials, you could dye each four times, for a maximum of 12 more points; 15 total. Of course, they have to be different paints per object, but they could be the same paint for different objects. In this case, you could dye each one black, white, blue, and green. In this way, each material acts as a "container" for up to four different paints.
At the end of every week, the player with the most points passes the test.
