A few weeks ago I picked up Control Eyeliner from Lush, which is described to be a deep inky-blue shade... and I don't think I've worn black since. This eyeliner is so different and versatile, I love it!
The bottle alone is freaking adorable! It looks like the potions from Alice in Wonderland with the little 'drink me' label on the side! To show how much I LOVE this colour, I haven't edited my photos at all! I've left them completely untouched so you get a proper, true to life, look at the colours you can achieve all from one little bottle!
