Rack
From YPPedia
A rack, which is located inside a tailor or a deluxe tailoring stall, lets other players try on clothing that is located on it. The tailor owner or managers may set the price of individual items on the rack, or mark them as "Display only". Furthermore, clothing does not age while it is on the rack.
Racks have a limit of 2000 items each.
