Maybe it's the packaging (which is matte black and lovely) or maybe it's the price (£8). Either way, I'd definitely recommend checking these out. There are four other shades in the line up, and I will most definitely be stopping at Topshop this week to take a peek at them! (read: buy one in every colour!)
