Wore this costume to Colossalcon 2014! Still have a couple things I want to fix and details I want to add, but I'm pretty happy with it over all.
100% wool gabardine was used for both the coat and the lining. The same purple wool gabardine used for the lining, is also used for the purple eyes/designs. I used two kinds of gold crepe back satin for the cuffs, triangle details at the bottom and the trim. Gold braid, piping and buttons were used for the front details. Brown pleather was used to make the large belt and the two smaller belts. I found matching beige shirting and bottom weight at Joann Fabrics for the underclothes.
I drafted a coat pattern from a bodice pattern that no longer fit me. I made a muslin mock up and drew roughly where all the designs would lie. I then transferred the coat pieces to pattern paper and finalized the designs (eyes, purple shapes, etc) and transferred those to bristol board, so that I could trace it to heat and bond. The heat and bond was then attached to my purple fabric, cut out and then the designs were heat and bonded to the coat pieces before being satin stitched down. I did all the satin stitching before putting the coat together, as this would make the pieces less bulky and easier to maneuver through the machine.
After satin stitching, I put the coat together, both the lining and the outside coat. This took some time, as I had to match the lines of the satin stitched designs to each piece, so it would look as if the design continued throughout the coat. I then matched up the coat and the lining and sewed them together. I then made the cuffs (which was a day of work in itself) and attached them to the coat.
I made my own double fold bias tape out of the same gold crepe back satin, and attached it to the edges of the coat with a Hong Kong trim, (so that there's no visible top stitching).
The shirt and pants were based off a generic pattern for both. I made a muslin draft of the shirt, then cut it up so that the finished product would have the seams (lines) going down the front. The details were just grey double/single-fold bias tape and buttons that were sewn on.
I had extra non-stretch brown pleather lying around from my Zack Fair fabric haul, so I made the big brown belt, and secured it with velcro for convenience. The smaller belts were made of the same material. The butt-skirt was made from the same suiting as the coat, the same crepe back satin is used for the gold designs.
Before I wear Robin again, I'd like to make the bolero pictured in the fan-made reference sheet, so that I could attach a new collar to it. I believe it'll sit more nicely that way. The designs on the butt skirt need to be satin stitched for consistency throughout the costume. I also want to make the boot covers, since I made the entire costume in about two weeks and decided against rushing them.
