I've found a really great Victorian-era etiquette ebook online that I thought a few of you may be interested in. It's great for "lifestyle" lolitas, and even if you don't adhere to the lifestyle (which I personally don't), it's still a really interesting read. It details how one should act and present oneself in polite society and on certain special occasions such as dinner parties, weddings, and funerals, and depending on which version you download it also has some great illustrations. So whether you take it seriously, or for the lolz, I think it's worth checking out.
You can find it here.
