All of my period knitting items use the conversion table and information written by Collen Formby. If you haven't read that article, it's a lifesaver when trying to create period knitting projects.
One thing about 1850s clothing that looks really strange to our modern eyes is the use of matching which looks excessive to us. For instance, it was popular for women to wear two identical bracelets, one on each wrist. Women might also wear a large "show piece" necklace with equally large matching earrings.Today we would consider the looks gaudy.
Unfortunately every once in a while, my historical wardrobe will sneak into my modern one and I'll find myself over-jeweled in a way that looks almost sarcastic today. Only one of the few problems with trying to be stylish in multiple centuries. :)
