Dwarves may have dark, brown or red hair, and their complexion is light and ruddy. Their skin is sensitive towards sunlight and they easily develop sunburns if they are incautious. Their eyes are different shades of brown or blue. The Mervin dwarves notably more often have red hair than other dwarves. Their surface dwellings among the hills has made them more tolerant towards sun exposure, but they still favor wide-brimmed hats for protection. Dwarves grow thick beards early in their youth. Shaving is exceedingly rare and is usually a sign of deep shame. The women often have sparser beard growth and they tend to trim their beards more neatly than the men do. Their styling varies more as well, and they may be seen wearing mustaches, goatees, sideburns or other intricate fashions. The beard is an important signifier in dwarven society, and its styling describes social status as well as heritage. Different regions have their own traditions as to how to wear their beards. The Dar'Kolbur dwarves typically braid and interweave metal adornments into their beards, while the Mervin dwarves usually keep them short and unadorned. The Arwondel city dwarves commonly braid their beards into one or two plaits using rings of metal or cloth to bind them. For everyday use, the dwarves favor practical and durable clothes in modest coloring. The Dar'Kolbur dwarves mainly acquire their clothing materials from domestic pigs and goats, yielding both leather and sparse amounts of cloth. Surrounding game also provides furs, which are greatly appreciated for their warmth. Mantles, gloves and caps of fur are a common sight. In rocky or icy terrain they can be seen wearing metal crampons to increase the traction of their boots. Padded clothing, especially around the arms, which adds pomp to the wearer's silhouette, is very popular among the upper class. The Mervin dwarves commonly dress in wool, which they shear from their sheep. They buy linen cloth from the halflings to wear during warm summers. In wintertime they wear their characteristic thick woolen sweaters and knitted scarves. The city-bound Arwondel dwarves have access to a more varied assortment of clothing material. They prefer lighter fabrics than wool, such as linen, and their clothes tend to be of more elaborate cut and coloring than those of their cousins. Dwarves seldom wear luxurious jewelry unless it is an heirloom, or is required by a formal occasion. They generally prefer well crafted practical items as adornments, such as buckles and bracers. Broad girdles and belts of good craftsmanship are particularly popular, and any dwarf of good standing is expected to have at least one. A common addition to the belt, or girdle, is the purse – a proud reminder of the dwarven Purse Federation. Aside from the styling of their beards, dwarves display their heritage and clan with heraldic marks and bright colors.
