I was so excited about my shoes yesterday I completely forgot it was Stuff Day! To make up for it, here's Stuff Day a day late.
I recently acquired a copy of this book, and it's great. It follows a history of fashion through the centuries with primary sources, not redrawn pictures. The information points out great details in the clothing that you may have missed that can make a costume truly authentic. It's not as inclusive or detailed as Boucher, but it's also not as expensive. It's a great book to add to a costume history library!
