Lightlys is pretty! I do also like white ponies a lot haha. That said, flipping the script and making the light version the evil one is a theme I am so here for.
And definitely on the goth/emo thing! I stopped wearing exclusively skull t-shirts, baggy pants, chains and spikes, and have taken up a large variety of styles including neon fluffy sweaters, but that definitely doesn't mean it's gone. :b If I could find a legit spike choker in the style I've always wanted, I would rock the heck out of that. That and my favourite bikini definitely happens to have skulls on it.
