I am planning on making: undergarments (short stays, rather then long), a day dress with removable long sleevses, an evening gown, a spener jacket with removable skirt, and a poke bonnet.
The undergarments are already in process with notes to follow soon. The day dress will be made out of a white handkerchief weight cotton that has a small floral print on it.
The evening gown will be out of the embroidered silk chiffon I purchased on my last District trip.
The spenser jacket will be out of a chocolate brown wool, again another District purchase. I don't know if it was period or not but I want to make the spenser jacket with a detachable floor length skirt. That way I can have the period jacket look and yet also have a long jacket for warmth if needed . . . Noticing a theme here aren't you? Well the event is in the desert in the middle of spring and the weather can be screwy that time of year. Either too hot or too cold or both. So I am planning to dress accordingly
I'm not sure where to start on the poke bonnet but I have seen and saved a few hopeful looking tutorials on easily creating one out of a modern straw hat and such. This and the turban are going to be where I will need to do the most research. And shoes of course, which I have not put any thought into, though Lauren of American Duchess just did a great post on dyeing and decorating her regency shoe "The Pemberley". That led to some interesting ideas ping ponging through the brain . . .
Everything else I feel pretty confident with . . . as long as I'm not rushing to finish, that is ;)
