Black and White Winx fashion

Yea I know I am suposed to upload my new Ocs and stuff I told you about, but they are still not finished and the storys are incomplete so *waiting for you I am so sorry* , here you have a sketch from this Winx fashion Style or how it is called for you. (that I upload something here). I had no idea how to colour it to it remains black and white. But I have to say I like it that way.

The Wings shape is the Sofix wing design from my OC Despina, but the girl is no Oc of mine it is just some random girl ^^
