Izannah Walker is generally known to have begun making dolls around 1845, even though she did not apply for a patent until November 4, 1873. A majority of the original clothing in which she dressed her dolls reflects the styles worn by children in the 1840’s and 1850’s. However, 1860’s clothing would also be perfectly appropriate.
To provide you with a bit of dress-making inspiration, here are some illustrations that appeared in Godey’s Lady’s Book in 1858, 1862, 1864 and 1866. In the future I will post some more 1850’s Godey’s illustrations, although the 1850’s illustrations are not as lavish as these from the 1860’s.
