On-line Book: Draping Period Costumes: Classical Greek to Victorian

ISSUU is a very interesting site that offers free e-magazines.  Some are full magazines and others are just samplers from the issue.  The link below is a complete book with tips on draping various eras of period costumes.  If you are interested in the 1840 and 50s, there are some nice styles.  The eras continue through the bustle period.  Hope this will be something you can use.
