Some time ago we published in your fantasy costume a post about this kind of shoes that are called Ghillies in our previous article "Medieval moccasins and ghillies for Highlanders, irish goblins and fairies".
Some pictures below so you can make an idea, and go and visit the step by step tutorial in Therese´s blog Earth and living.
Isis is a Goddess of Ancient Egyptian mythology and often is represented with this wings... thus the name of "isis wings" commonly used in bellydance. But even if you're not a dancer, this element will make your costume astounding!! A fairy, a goddess... its movement and ethereality is amazing. In one of my performance I shared the stage with my friends the Karinae Tribal troupe and as I use an opaque black isis wings they went on with organza black ones... of course they were amazing with them....! and I fell in love with these wings. In this picture you can see me performing with the Karinae wearing the isis wings.
