In those days, this was the closest to the shape of Esther's sister uniform in novel, however, the parts and accessories were minimum just to cover the Tri-Bla look. So of course there are no versions or the particular picture I tried to make this look like.
Later on I discovered that it was much more fun to make parts-accessories than making clothes/dress for TB costumes.
The material choice is for stage presentation and same as the wedding gown material.
