dimension: that Friends should not use more than their fair share of the Earth's limited resources. Like many aspects of Quaker life, the practice of plainness has evolved over time, although it is based on principles that have been a lasting part of Quaker thought. These principles now form part of the Quaker testimonies. Plainness is an extension of the testimony of simplicity and can still be observed today among modern Friends who do not follow fashion trends or purchase extravagant clothing. This testimony also finds expression in the tradition of plain walls and functional furniture in Quaker meeting houses. Simplicity in dress Traditionally, wearing plain dress was an answer to a number of Friends' concerns. Expensive styles were used to show social inequality and make statements about wealth. Only a select few could afford expensive adornments, which could then be used to exacerbate differences between people based on class, where people in fancy clothing would not want to be seen socializing with others dressed tattily. This was part of the inspiration for the Quaker testimony to equality. In addition, the frequent buying of expensive new styles and discarding what had recently been bought, was considered wasteful and self-seeking, where Friends instead aimed to focus on simplicity, and the important things in life. Notably, Friends did not consider it right to judge people on their material possessions, but this could not be achieved in a society which placed an emphasis on keeping up to date with inconsequential but expensive new trends. At the time, this practice of plainness meant Friends were obviously identifiable. As fashions changed over time, the Quaker ideal of plain dress stood out against contemporary clothing. As a result, the traditional forms of this practice were dropped by most Friends. Today, it is more likely that Friends will try to put their faith into action by dressing in a plain version of current fashions—such as avoiding clothing displaying designer labels. They may also try to buy only the clothing they need, and pay more for fairly traded clothing that has been made ethically. Friends used to have a strong tradition of simplicity in dress, more properly called "plain dress". Plain dress generally meant wearing clothes that were very similar to Amish or conservative Mennonite dress: often in dark colors and lacking adornments such as fancy (or any) pockets, buttons, buckles, lace, or embroidery.
