Sometimes one just needs to chill out and do some hand sewing. Here is a camicia (or smock, or shift, or chemise) from late 16th century, early 17th century Italy made in historical-y practice.
The books I reference are:
Patterns of Fashion 4: The cut and construction of linen shirts, smocks, neckwear, headwear and accessories for men and women c. 1540-1660. by Janet Arnold
Cut my Cote. by Dorothy K. Burnham
