Take note of the way pleats and lace are used on the skirts, and the variety of collars. And while you are considering the serious underwear these women had to have on to get that silhouette, don't forget about how straight you'd have to stand to hold up those hats! 
This plate has no information either, so once again I hope a kind reader fills us in. But it's clear they are at a party, maybe a masquerade ball? You won't be able to miss the aprons or the hats, but look closely and find the pockets, the purse, the bows and all that handwork. Wow. 
I have no information about this page, but these hats are lovely. I hope somebody comes along who can guess at a date. 
This shows a young lady in her fancy ball gown and her more demure friend in the Late Victorian fashions of 1860. This plate has lots of information, but it's all in French. I tried Google Translate and got this close, but I'm sure somebody out there can do better. It is dated February 11, 1860 and numbered 3122.
