Here's a link. Actually, this simple pattern would do for many different dolls. Just scroll down for the various kinds of clothing.

Here is a link that might be useful: Amish (and other) Dolls

I have a book "Patterns for Making Amish Dolls and Doll Clothes" by Rachel Pellman and jan Steffy. It is a 200+ page soft cover book that has patterns for both 20" and 12" dolls, adult and child dresses, adult apron, adult cape, childs apron Adults and childs covering, bonnets, slip, panties, shoes, shirts, plain coat, pants, vest, hat, nightshirt, boxer shorts plus a mini doll and all it's clothes. These are very close to authentic Amish clothing. The cover price on the book is $12.75 but I just checked at www.half.com and there's one there for $1.49!!! I'm pretty sure it's has to be the same book. It's the same authours, same copywrite date (1987) and gives a list price of $14.95. (I've had mine for quite awhile) I made several dolls from it and it's a very nice book.
