Q: This book dates back to the civil war era. It was the fashion source that women turned to for the most current information on what to wear. If you have ever wondered what they really wore, and why they wore it then I would suggest that you look to these books for the answers. Typically these books have a full year bound together. Each month should have a color fashion plate featuring the current wardrobe fashions. They also have music, poems, short stories, knitting and crochet patterns, health tips and cooking hints. They provide a valuable insight into the era. If you are a civil war reenactor there is no better source for accurate information, and if you are just a fan of American history, these books are an outstanding source.
A:
Positive
