I wanted to write this out but fashion-era’s site is very comprehensible. So here are three links which will show you how hair was worn during the nineteenth century!
A site with many articles on everything hat-related:
“Wearing every article of the same colour is fashionable only on condition the strictest uniformity of tone is maintained. “There is nothing more distressing than seeing a dress of deep blue, inclining to purple, with a bonnet with sky-blue ribbons.”
Unrelated: Catherine Sherman posted a review on a book which seems very interesting: Kate Summerscale’s “The Suspicions of Mr. Whicher.” you can read the review here. The book is a detective novel, set in 1860. It’s definitely on my to-read list! (On Amazon)
