Well, since you asked so nicely....
Ok, to start with let me state a rule for the budding costumer: thrift stores are your best friend. 90% of the bat suit was put together from thrift store fare. I went down a bought all the leather and pleather coats and pants I could find that fit me. I then took everything apart with a seam ripper and scissors, except for the base top (jacket). That i just took off the sleeves. I took sleeves from another coat, with stretchier pleather, and attached them backwards onto the top. "Backwards?' you say. After putting a length of shoe lace on the zipper i'd put the top on backwards and pull. Vio'la! just like a wet suit. I also sewed a piece of the pleather at the crotch so it REALLY looked like a wet suit.
The leather pants were cut apart and glued to spandex pants.
So far, all thrift store stuff. I also found a pair of boots (women's) there and cut the top part of to make spats that would go over what ever shoes/boots i wanted to wear.The gloves were 6 bucks (thrift store as well).
Useing more pleather, I made a hood, to which attached BB 3/4 cowl from Rubie's and used more pleather to cover the edge.
The forearm guards are stock Nike pads with cut and painted Foamies craft foam glued to them. the buck bat and boot bats are painted foamies, as well.
The web belt and buckel were bought at Joanne's Fabrics. The pouches you know about, and the cylinders between them are Dollar Tree bubble solution containers sprayed with Plasti-Dip.
And last, but not least, the chest emblem is painted pleather, glued on.
The armor, underneath, is cut sections of Foamie.
The cape was made using a cloak pattern then cutting the scallops.
Any questions?
