Carte De Visite from C.1861-1865. Note the
military influence on the bodice of the habit with all the decorative frogging across it. This was a popular fashion for riding habits for most of the 19th century up until the 1870's. Note also how long her skirt is. Until aprons became shorter and more tailored during the latter half of the 19th century, women had to carry their skirts when dismounted. When mounted, the aprons looked incredibly elegant even though the skirt could hang down as far as the horse's knees!
