To tide you over, here's a lovely fashion plate of children's clothing from October of 1875 (source uncertain, unfortunately). I haven't come across a lot of fashion plates for children, which makes this one interesting. Mostly children wore rather amorphous dresses until they were about 7 or 8 years old, then they generally wore miniature versions of whatever was fashionable for adults.
Love the colors: the blue shiny stripes and the gold/coppery combination. It seems I have not posted much from this era, which is interesting since it's so smack-dab into Reconstruction-era America, but maybe I have just been saving this stuff for when I get there. I feel right now like I will never get out of the 1850s. Gotta move this ahead quicker!
