Cosplayer Anime_freak_kai definitely didn’t go renegade when he made this Shahkulu costume from Assassin’s Creed: Revelations. The helmet is made from Wonderflex and craft foam and all those details were etched into the foam! The precise embroidery on the tunic is insane, and he said that was the most complicated part:
Tunic- Definitely the most complicated part of the costume. All the embroidery (trim, frogs, and smaller details) was done entirely by hand, and the bordering is multiple layers of machine satin-stitching. I used about 7 full spools of gold thread for it. The tunic is in two pieces, the entire top is one piece for convenience (undershirt, sleeves, red/white tunic, and shoulder cups) and the flaps below the belt are separate. The top was hand-stitched over the grey undershirt and a zipper was hidden in the front. The flaps attach to the belt via snaps. Craft foam was used as interfacing for the white tunic since it was stiff and flexible enough. Wool felt was used for the grey undershirt and pants. Linen and a dyed patterned linen was used for the white tunic.
