This is a French Fashion design called Worth Chateau Toilette for the year 1892.
The skirt hitches up on one side, and is shorter there. Otherwise their is a petticoat underneath, that peaks out on the side.
I used a deep blue to make up this gown. There is a train in the back. The lovely hat has a long veil, and flower and berry decoration. Again there is an underdress, and an overdress.
A bit involved, but then what French Fashion wasn't?
