Anna Chepsarakova, also known as Lleye Cosplay, has an extensive cosplay portfolio. She’s cosplayed characters from nuns to witches and just about everything in between. She doesn’t have any tutorials in her portfolio as far as I can tell, but it’s still worth flipping through for the sake of seeing all the possibilities and to view her skill range. She’s talented at making costumes, styling wigs, and applying killer makeup. Her ensembles range from somewhat simple (see the Olive Moore costume from iZombie pictured below) to more complex. The Ragnarok Online Banshee dress pictured above looks like it was an elaborate build.
I’ve included a few examples from Lleye’s costume resume below, but you can follow all of her work on Patreon, Instagram, or DeviantArt.
