Mennonite, and Brethren church groups in Lancaster County). What is acceptable in one community may not be acceptable in another. Groups may separate over matters such as the width of a hat-brim, the color of buggies, or various other issues. The use of tobacco (excluding cigarettes, which are considered "worldly") and moderate use of alcohol are generally permitted, particularly among older and more conservative groups. Language In addition to English, most Old Order Amish speak a distinctive German dialect called Pennsylvania German or, much more commonly, Pennsylvania Dutch. Pennsylvania German is related to the Palatinate German of the 18th century. It has also been strongly influenced by American English. The English term "Dutch" originally referred to all forms of German and Netherlandic languages. Pennsylvania German, which is a High German dialect, is distinct from Mennonite Low German and Hutterite German dialects spoken by other Anabaptist groups. Now spoken primarily by the Old Order Amish and Old Order Mennonites, Pennsylvania German was originally spoken by many German-American immigrants in Pennsylvania and surrounding areas, especially those who came prior to 1800. There are also several sizable Old Order Amish communities where a variety of Swiss German is spoken, rather than Pennsylvania German. The Beachy Amish, especially those who were born roughly after 1960, tend to speak predominantly in English at home. All other Amish groups use either Pennsylvania German or a variety of Swiss German as their in-group language of discourse. There are small dialectal variations between communities, such as Lancaster County and Indiana speech varieties. The Amish are aware of regional variation, and occasionally experience difficulty in understanding speakers from outside their own area. Clothing The common theme among all Amish clothing is plainness; clothing should not call attention to the wearer by cut, color, or any other feature. Hook-and-eye closures or straight pins are used as fasteners on dress clothing rather than buttons, zippers, or velcro. Snaps are used on everyday clothes, and plain buttons for work shirts and trousers. The historic restriction on buttons is attributed to tradition and their potential for ostentation. Some groups tend to limit color to black (trousers, dresses) and white (shirts), while others allow muted colors. Dark blue denim work clothing is common within some groups as well. The Old Order Amish often sew their own clothing. Women wear cape dresses, calf-length plain-cut dresses in a solid color. Aprons are often worn at home,
