But I had to dress Inez appropriately for venturing out of her hotel room in Manitou, Colorado, on a fine summer morning in August 1880. And, as often happens when I'm faced with such a requirement, I scurried first to my bookcase, and thence to the internet.
Thus was my doom sealed. It all went something like this:

All well and good.
And wow, there are a lot of neat hairstyles here for 1881. That's pretty darn close to summer 1880... I better bookmark this site...
Oh hey, look at the bottom of the page: I have THREE of the books listed! (Now that makes me feel pretty good...) But, hmmm. Here's one I don't have: Dressed for the Photographer: Ordinary Americans and Fashion, 1840-1900. I can't believe that I don't have this... Well, I'll order it. Hmmm. I can get it in combination with Uncovering Your Ancestry through Family Photographs. I bet they have some good stuff on looking at the details in old photographs....
Before I'm done, I've ordered four books in all, nearly a hundred dollars' worth, and made two return trips to my bookshelves, scanning for Dressed for the Photographer. I really have the sneaking feeling I've got this book somewhere. How could I not?? It's been around since 1997 and is right up my alley, so to speak.
Okay, now back to the scene and the critical bit of dialogue it's all leading to. I'll tell you, though, if I find that book in my shelves tomorrow, I am going to be mighty pissed.
