Sewing Tips and the History of Underwear

I tried to find a unifying theme for this collection of sewing links, but they are a miscellany, saved for miscellaneous reasons. Here we have pattern alteration tips, lingerie patterns, costume resources, and the history of underwear in the twentieth century. Enjoy!

• Debbie's Sewing Tips and Project Instructions. Good explanations, good pictures. I found the full bust adjustment section particularly useful.
• Sewing Lingerie. Patterns and notions for sale. I haven't tried these, but other sewing bloggers like her patterns very much.
• Corsetiere.net presents an astonishing amount of information, primarily on the history of ladies' undergarments in the twentieth century. One can read for hours and not see everything. The authors say:

  The original idea was to publish the fascinating history of Spirella and the corsetieres who worked for this company before knowledge of the era became lost forever....As the compilation of this web site progressed, we began to realize how little we knew about this fascinating era....I am always grateful to correspondents who correct me when my assumptions from the east of the Atlantic contradict those from the west.

• Laughing Moon Mercantile has authentic period sewing patterns for Western, Civil War, Edwardian and Victorian wear. If you're interested in foundation garments of the past, either from an engineering or historical view, period sewing patterns like their ladies' Victorian underwear are instructive. They also offer links to other costume sites.
