I made this outfit about 9 years ago, and I syill wear it to events today.
Both the coat & skirt are made from 18 gauge wire wrapped to 3/8" I.D. except were otherwise noted.
The tailcoat is made from 36,864 stainless steel rings and about 100 3/16" I.D. brass rings for attaching the leather collar and cuffs. The buttons are gold tone and go through working button holes, and the sleeve is semi-fitted.
The skirt is made from 14782 aluminum rings, and 3890 stainless rings. The stainless rings are woven European 6in1 for a sturdy waistband. The aluminum is woven in 8 panels of hexagonal expansion (like you'd do for the top of a coif), to give the skirt a slight over-gore for a very nice swing and twirl when moving.
The tailcoat weighs 18 lbs. and the skirt is another 3 lbs. This makes for a total weight of 21 lbs., before adding corset (the extra back support is nice when wearing this), underwear, petticoat, shoes and whatever other accessories one chooses to add. Any activity becomes an instant workout, but it looks darn good!
