I was looking around the web and found this one full of probably hundreds of Victorian Portraits and photographs from a British Professional Photographers' collection. There are some amazing photos for ideas and validations on costuming.
This is another one of my favorite sites for loads of costuming help. Free patterns, photos, fashion plates... it is a wealth of information.
And finally, I found this short history on Buttons (from the BBC) enlightening.
I appreciate the work you do on the blog. I do go there and read through the articles. I love the vids from the NM museum.
