I am making a Tiefling Warlock costume with the intention of wearing it at GenCon this year. I am still working on the horns & tail. I need to start on the leather armor soon, though I need to choose boots to put armor over. I have a design for the staff, but have not yet started on that either. I have quite a few months so i can take my time!
Here is the necklace and what I have of the robe. The silk underskirt won't be worn when I wear armor since it would hide the leg armor. The black is linen. The silk trim you can't really see that it is shot silk in purple & blue. It's hand cut from scraps, ironed, serged, then ironed again before being applied to the linen. The silk skirt & sleeves are made from 2 tone crepe back silk satin. Turquoise on one side & indigo that doies colour shift a bit on the other. You can just see some of the turquoise indise the one sleeve.
You can just barely make out a pair of bootwings temporarily clipped to the corset straps. I am going to do some detailing on those & mirror some of the pointy/swoopiness in the armor pieces.
The fabric on the floor infront of the dress may or may not become the lining of a cloak to wear with it.
