ITEMS
Some items we would really like to see (pm me to add to this list):
Women:

Bonnets:
Gaia Online currently has only one bonnet, the pilgirm bonnet. This looks nothing like the bonnets mostly worn while bonnets were in fashion. Below are some pictures of bonnets that were popular during the Regency time. Note: A Bonnet should really have a bow that ties under the chin. I believe the bonnets on Gaia should be able to be worn with or without the bow.

And from a slightly later period
Sun bonnet
Elegant hats-there really is a lack of elegant hats, which are still popular even today, espicially at the races
Victorian Touring Hat
Dresses: The classical Regency dress. Elegant but simple.
Petticoats: nothing like a little lace peaking from under a maiden's dress to get the men's hearts pumping
Petticoat
Hoop Skirts: Sure they are akward to sit down in and no one will be able to get near you, but they sure look lovely. From various periods, making a comback today in many wedding dresses (including my sister-in-laws) they transform your skirt into a big round thing
Bustles:
Corsets:
More hairstyles, to go with our brand new clothing.
Men:
Tailcoat: Very dashing coat, in various colours. The army wore red ones, and were hence known as Redcoats.
Boots over pants: While there is a large selection of men’s boots but none of them go over pants. Let us Tuck our pants in, and show off our awesome boots. No decent regency gentleman would not have tucked his pants in!

(Image stolen from "Tuck in your pants petition" I'm sure they don't mind.
Spats:
I would appreciate anyone who is talented in such area to create models of potential period clothing.
